If by "asynch" you mean keeping your application alive and running

needed.


Rough idea (untested):

local postUrlQ
local asynchPostRunning = false

on someHandler
 ---code

put the result into tRes

That's likely to be it. Derek's iMac is an original iMac, and this
procedure (reset cuda chip) is a likely fix (assuming the keyboard is 
OK). Later models are a bit different though, the battery is also involved.

Re: Asynchronous upload via post?

[Andre Garzia]

Dave,

thanks for the tip! I use a similar approach for queueing downloads, it
didn´t occur to me that I could do the same thing with POST calls.

I noticed that the load command will queue connections to the same server
automatically, is this correct or am I dreaming?

Again, thanks for the hard work with LibURL! :-)

Cheers

using time of day (was newbie videoplayer questions)

[d]

ok, I'' try again, see if it gets to the list.
 time is running out for me since I have an exhibition on saturday  
where I wanted to use this.


I have been playing around with the time script I got from klaus and  
others

First I tried it with cards and one stack instead of several substacks
I put the time script on every card because it has to check what the  
time on opening each card.
and it works great until the time crosses the 12:00, 18:00, 00:00 line 
( the time of change-over to the morning, afternoon or evening  
part) ; then it starts to flip through all the cards and I can't stop  
it without quitting.
when using substacks it works because the stack closes before  
anything bad can happen but I do notice a quick flip-through-the  
cards at the same moments in time as with the cards version.

here's the script I am using. any ideas?

best regards
eddie d

  set the backgroundColor of this card to "black"
on opencard  --sthecorrectstackaccordingtothecurrentdaytime

   set the twelvehourtime to false
   put the time into tTime
set the itemdelimiter to ":"
put item 1 of tTime into tHour

if tHour >= 0 AND tHour < 12 then
 go card "morgen_1"
end if

if tHour >= 12 AND tHour < 18 then
go card "middag_2"
- end if

if tHour >= 18 AND tHour < 24 then
go card "avond_1"
end if
end opencard


on mouseUp
  start player "tardes"
end mouseUp

on playStopped
  go card "middag_2"
end playStopped

Hi Andre. Yes, that's right. (You may be dreaming too, but about  
other things I hope.)


Strictly speaking, ftp load requests are queued separately for each  
account (username-server), but in most cases it amounts to the same  
thing.

My suggestion would be to set up your own cache system instead. It's  
not too difficult. Use a customPropertySet or script local array to  
store the data, and use the url as the key. Then you just need three  
handlers/functions:


getFromCache 
storeToCache 
deleteFromCache 

Then just use get/post URL, or if you use load, after putting the  
data in your own cache, unload the url.


But if you want to tamper with libUrl, and understand the danger that  
if you get too familiar you may be asked to take it over, and accept  
the usual "at your own risk" warning, and understand that your  
changes may not work in future updates and that you may turn into a  
frog...


... you could probably add a handler to liburl that would need to  
touch 2 script local variables. These are laLoadedUrls and  
laUrlLoadStatus. These are both arrays, and the keys are the relevant  
url itself. Put the data to be cached into laLoadedUrls[yourURL] and  
set laUrlLoadStatus[yourUrl] to "cached".

abort scripts

[runrev260805]

Hi,

i have some questions again.

How can i stop the execution of a script. e.g. I want to stop executing a 
script, which is already started by mouseup event.


Another thing is: I have a very large mouseup script, I want to destroy the 
stack, when a special condition takes place. But the script continues. I have 
set "the destroystack property to true".
Found out, that this behaviour is normal, because the "close" statement is in 
the same event handler. But how can i solve this. Do i have to send a message 
to another obejct, which contains the "close" statement?

I need to delete files in a folder. The names of the files vary. I thought i 
could use wildcards to delete, but that doesn´t work. Do i have to read the 
content of the folder, put this in a container/var and then delete within a 
repeat loop? Or how can i do this?


Regards,

Matthais

If you're trying to close and remove the stack that's current running 
the mouseUP script, you *should* be able to just say "close this stack" 
in the script of your mouseUp handler and it should work. However if it 
doesn't, send a custom command to the same object ("me") in a short 
time (like 100 milliseconds), and then immediate do an "exit to top", 
which will get you out of the mouseUp handler you're in. Something like 
this:

on mouseUp
  -- do a bunch of stuff
  -- if the condition is met (I'm imagining the 'tCondition' variable 
starts off
  -- false and when the condition is met it gets set to true
  if tCondition is true then
send "closeMe" to me in 100 milliseconds
exit to top
  end if
  -- more stuff that could happen if the condition wasn't met
end mouseUp

on closeMe
  close this stack
end closeMe

Yes, that's the best way (switch the defaultFolder to the folder you 
want to delete files from, put "the files" into a variable, switch your 
defaultFolder back to where it was, then loop through the list of files 
in the variable identifying the one(s) you want to delete, then delete 
them).

how do you mean?  Manually, or programatically?

I  use (during debugging/design)
if the optionkey is down then breakpoint  --then click abort
or
if the optionkey is down then exit to top  --then click abort

in your case, one technique that could work is

send "closeme" to this stack in 1 second
exit to top  --ends all handlers

You need to tell us what you think 'destroystack' means to you.  It probably
means something different to Rev.  (be specific, if possible)

set the defaultfolder to theFolderIwant
put the files into fileList
filter fileList with "*temp*.*"
repeat for each line LNN in fileList
   delete file LNN
end repeat
put the files into remainingList

OT strange tech support calls

[Shari]

In a recent thread, I commented about the tech support issues that 
come up, where some users do not understand very basic concepts.  And 
how I wouldn't want to add to it by having to put out multiple 
versions for one platform.


Today's never-before-encountered tech support issue:

His platform:  Mac OSX 10.4.9

His problem:  He couldn't find a menu item in my software.  He 
claimed that the menu itself did not exist, that there was absolutely 
no menu of any kind, whatsoever.


After several go-rounds, I requested a screenshot of his full 
computer screen while running my software.  He sent a screenshot of 
the program's window only.  Of course on a Mac, this wouldn't show 
the menubar.  After requesting again a full screenshot, we found the 
problem.


The menu existed.  But he was expecting it to be in the window 
itself, rather than at the top of the computer screen.  Even though 
several of my emails to him told him to look at the top of his 
screen, he failed to understand until I asked for a screenshot.  Then 
he figured it out, and apologize profusely.


Am not sure if he is a Windoze to Mac switcher, or simply a computer newbie.

My users range from his level of expertise to highly technical folks. 
But I try to keep the software understandable for all levels of 
usability.

I'll go out on a limb just as I did several years ago when I suggested 
Apple would eventually adopt Intel processors and two-button mouse 
functionality:


Somewhere between OS XI and OS XII it seems likely Apple will move the 
menu bar to the tops of windows.


Sure, this seems heretical right now, but the usability studies showing 
the benefit of the current menu placement were done with the Mac display 
was 512x342, and Fitts' Law suggests that as displays get larger the 
benefit of the "backstop effect" of the monitor bounds diminishes with 
distance to the target.


If any of you have links to current usability research on menu bar 
placement I'd be very interested to read it.

Yep, I agree. With those HUGE and MULTIPLE displays, it is actually more
difficult to mouse to the top of the main display. Perhaps we'll see more
ribbon-like menus for the Mac.

Image Tile Cutter

Re: Asynchronous upload via post?

[Stephen Barncard]

Dave, Jacque, please explain more... if one wants more 'threads' one 
needs separate scripts?


I kinda know this works but I need to define it...

so if one trys to do a blocking thing, say, in the bg script, then 
any handler in that script is halted?


but if one does a "send in x"  a command to an object, say button or 
field or whatever from the same bg script, the script in the btn 
executes and/or blocks while the bg script continues?


What would be the best repository for such "little" scripts? Hidden 
buttons? Backscripts?


is there a way to pull a script from a custom prop and 'do' it 
(within scriptlimits of course) in a runtime? I couldn't get this to 
work.

revMessageBoxRedirect

[David Bovill]

This is a currently unsupported feature which looks quite useful:

the revMessageBoxRedirect

~

This global property allows you to configure what happens when the value
of the 'msg' pseudo-variable changes.

When set to empty, the old behaviour will be used.

When set to the long id of a field, the old behaviour is replicated but
instead of 'msg' being put into field 1 of card 1 of stack "Message Box", it
is put into the target field. (Note that this form will also cause the
field's stack to be modeless'ed and raised).

When set to the long id of a non-field object, the specified object will
receive a 'msgChanged' message meaning that you have complete control over
what to do with the updated value of 'msg'.

NB. This property is only available in the IDE engine.




However if I:

set the revMessageBoxRedirect to the long id of this stack


A "msgChanged" is sent to the stack but without any parameters so I don't
know what the message was? Any ideas?

Re: Delimiting thousandths..converting 12345678 to 12, 345, 678 for example

[Jim Ault]

Hello, Hugh,

In my last script, I did accommodate the comma/period alternative by using
"itemDel" to form the result string, therefore the default itemDel for Rev
would be comma thus if pSeparator was "." just use the default of "," for
the decimal separator.

 if pSeparator is "," then set the itemDel to "."
 --  should be the only line required
--since, the itemDel is comma by default at the start of the function
-

As far as "0.00", the user may not want the decimals changed to that format.
We do statistics work, and often want only  0 or 1 decimal and no
reformatting of the decimals by a function.  If there is no decimal in pNum,
it returns no decimal.  This would be true of inventory reports, number of
skiers injured in the Alps each year, Rev programmers I have met in person,
the number of drivers that go fast on the autobahn.

...which means my prev function should have one line corrected:
if holdDec is not empty then put holdDec into item 2 of it
--if there is none, don't add the trailing decimal point.


If this is indeed a currency function, then I guess this is the spot where
you would have to define the function precisely, such as pNum must be a
number, instead of a number string to which we are adding commas.

(eg.  $3456.78  or -$3456.78  or $3456.78 - )

By capturing the leading and trailing characters verbatim, this should
accommodate 
--any currency symbol passed as part of the string pNum
--negative symbol format as trailing
--any number of chars after the decimal
but you are correct in that my version would not insert a currency symbol or
format "0.00"

Of course, this is why universal functions are difficult to write.  A tool
for many purposes may become less and less convenient.

Re-2: abort scripts

[runrev260805]

Thanks Jim,
thanks Kray,

that did it.

Let´s assume i have a stack with 4 buttons. 1 Button just quits the app. How 
could i close(destroy) the stack, if one handler of one of the 3 other buttons 
is active and i don´t know which button was pressed. 

Should i include something like "put the name of me into btnName" in the 
mouseup handler of this 3 buttons?  I could then check the global var btnName 
and i know which button was pressed. Or does Revolution has an internal 
function for that.

Re: Image Tile Cutter

[Stephen Barncard]

a simple way I would think would be to create an invisible or 
offscreen stack to the full size of the image (up to 4000x4000 I 
think), set the filename of the image to the big file, create a grid,


and use

export snapshot [from rect[angle] rectangle] [of object] to {file 
filePath |container} [as format] [with mask maskFile]


Examples:
export snapshot to file "Test.ppm"
export snapshot from rect "0,0,200,200" to file "Nav.jpg" as JPEG

export snapshot to pictVariable as GIF  (this could be saved as as 
custom property, or the picVariable could be an array, each square 
saved in an element which comprises the whole graphic. then could be 
saved as a custom property set, ready to go)


hmmm...

gotcha's? I don't know.. seems like it would work.

Can I Stop Non-List Fields From Scrolling?

[Gregory Lypny]

Hello everyone,

I've noticed that non-list fields without scroll bars still scroll up  
and down when I move the scroll ball on my Mighty Mouse.  They even  
move a little when there is only one line of data in the field and  
only one line visible.


Is there any way to stop this?  A client can inadvertently move the  
contents of a field out of sight without knowing it, and not know how  
to get it back.


Regards,

Gregory

min() function anomalies

[Shari]

This may not affect any of you, but I discovered a change that has 
sent me scurrying thru a lot of hoops wondering why my code was 
broken.


The original Metacard handled the min() function as Hypercard once 
did.  But later versions handle it differently.  If your program was 
originally written in Hypercard or Metacard and ported to Revolution, 
you might be affected by this.


The min() function returns different results depending on the engine version:

min(1,2,3,4,)   # note the extra comma

Hypercard 2.4.1 = 1
Metacard 2.4.3 = 1
MC/Rev 2.7.4 = 0
MC/Rev 2.8.1 = 0

I do not know if Rev would consider this a bug, or a "feature".  Does 
anybody know?


max(1,2,3,4,) produces 4, as one would expect.

Export Snapshot (was Re: Image Tile Cutter)

[David Bovill]

My experience of export snapshot is that the results are a little dependent
on something to do with the users machine - I am not sure if I am just
thinking here - but the tests I did seemed to indicate that there were
subtle changes in colour or rather the contrast of the image - can anyone
elaborate?

If the field is editable at all times, then I don't believe there is any to
prevent scrolling.

If you can employ a "locked state" to the field, one way would be to overlay
a graphic with a noop ink applied to it above the field so that no mouse
events reach the field.

Re: min() function anomalies

[Jim Ault]

You always have to be wary of trailing delimiters.

the number of lines, items
min(), max(), sum()

Look for the empty "last" item/line you want to keep, if needed.
put item 1 to -1 of dataList into dataList  --drops the last delim

Not sure if it is a bug or feature, but is an issue in some cases.

Joe  Wilkins


What bothers me is that almost any repeat loop that builds a variable 
will have a trailing comma, so I would expect the engine to ignore 
it, as was done in the past.  (Key point - that in the past this was 
handled differently.)


global myVariable
repeat x
  put someNumber or someOtherThing & comma after myVariable
end repeat

I use this type of handler frequently.  Whether it be numbers or 
words doesn't matter.  Yes, it can be worked around, by deleting the 
trailing comma at some point.


If you have a number of handlers that add to the variable at 
different times, this gets more ticky.


What bothers me more is that somewhere along the way, it was * 
changed *.  This is a very fundamental change.  I do not know if the 
change occurred before the MC/Rev merger or after.  But either way, I 
wouldn't have expected it.

Hi Gregory,
As far as I know, Scott is correct.  The next best thing is to
put a mouseup and a mouseleave handler in the field and put
'set the vscroll of me to 0' in each of those handlers.  Your
clients will still be able to scroll the field, but they will
not be able to leave it in a state of scroll.

Re: min() function anomalies

[Joe Lewis Wilkins]

I am inclined to think it was an accidental change; hence a bug,  
since whenever I've written anything that had the potential of  
generating a trailing delimiter, I checked for it, and deleted it  
before proceeding. With Rev, this was just overlooked; something  
fairly easy to do - IMHO.

Normally any field whose contents extend beyond the visible bounds of 
the object will be scrolled in response to a mouse scroll wheel.


The rawKeyDown message is sent when the scroll wheel is used, so you can 
trap the appropriate values (65308 is "scroll down" and 65309 is "scroll 
up") to prevent scrolling:


on rawKeyDown k
  if k is not in "65308,65309" then pass rawKeyDown
end rawKeyDown

But maybe even simpler would be to remove the empty lines from the 
bottom of the field text.

I agree that any change to a token's behavior should be documented.  If 
it changed during RunRev's tenure, it should be noted in their 
Dictionary entry for the min token.


I do see one change there noted as introduced in v1.1, but that's for 
something else.  I don't see any mention of this change in their docs.


Shari, I'd suggest submitting this as a documentation request to BZ.  It

Check out my old stack "Picturepuzzle", where among the scripts you find 
one of many possible ways to cut a picture into tiles. Stack is from 
2003 and produced with Metacard 2.5, but should possibly run with newer 
versions (did not test that), but in any case you can read the scripts.

I just remembered an old stack I did a while ago that takes an image and
creates tiles out of it using a cropping method, as opposed to a
screencapture or imageData method.  It was intended to test out an idea for
a transition effect of displaying an image made up out of tiles, but perhaps
it's one way to get you started.

No, you're right on how to handle that. Normally "the target" would 
tell you the last button pressed, but as soon as you click the button 
that closes the app, the target changes to that button instead.

I'm assuming that the code in the other three buttons are asynchronous 
in some way so that you actually *can* click the fourth button while 
another button's script is running?

Yes, I've gotten in the habit of deleting it immediately:

   global myVariable
   repeat x
 put someNumber or someOtherThing & comma after myVariable
   end repeat
   delete char -1 of myVariable

In fact, I even have a separate handler to save me from having to type 
"delete char -1 of " all the time; it's called KLC (kill last 
character):

on KLC @pWhat
  delete char -1 of pWhat
end KLC

That way, I can do:

  KLC myVariable

 and immediately following this command, myVariable has been trimmed 
appropriately.

Re-3: abort scripts

[runrev260805]

Hi,

Maybe someone knows.

I have a stack with one card. The card contains 4 Buttons. 3 Buttons start 
routines, which take about 5 minutes each to finish. Clicking on the fourth 
button shall abort the running sript of the button, which was pressed.

Thought, i could solve this with 'send "exit to top" to button btnToStop', 
where btnToStop contains the button name. But this does not work.

How can i achieve this?

I will report it.

I wouldn't call it minor however, as anyone who is porting an 
existing project from either Hypercard or the original Metacard 
wouldn't expect such a change, nor would they be likely to look up 
this function in the docs.


When my code broke, even when I narrowed it down to the one line that 
included min(), I did not assume the min() function was the culprit. 
I assumed that something else in that line of code was in error, 
perhaps a misplaced "(" or some other variable with a wrong value. 
It was a bugger to track down.


As I often see folks coming onto the list asking about porting stacks 
from HC or MC into Rev, this could affect all such folks, and 
wherever the documentation or tutorials exist that walk folks thru 
the change, this notation should exist.


For original Metacard pre-merger stacks, those folks probably 
wouldn't even read a tutorial.  They would expect it to just "work" 
as I did.


Off to BZ.

Assuming your routine is a loop of some kind, you could do it by setting a
custom property of the card, similar to this:

[routine button scripts]
 on mouseUp
   set the allowProcessing of this cd to true
  doMyRoutine
 end mouseUp

 on doMyRoutine
if not the allowProcessing of this cd then exit to top
-- do myStuff
send "doMyRoutine" to me in 5 millisecs
 end doMyRoutine



[cancel button script]
 on mouseUp
   set the allowProcessing of this cd to false
 end mouseUp

Just for the record, the "number of" function works properly as it did 
in HC and MC: the number of items in "1,2,3,4," is 4. So it looks like 
the problem is only in the math functions.


However, look at this:

  put min(1,2,3,4,) --> 0
  put min("1,2,3,4,") --> 1

Maybe all you have to do is add quotation marks.

Sorry. I was unclear. Only the *handler* the blocking call was made

The following may illustrate how blocking calls in libUrl work (needs  
button and field). Normally "send .. in 0 milliseconds" will only  
invoke the called handler after the currently running handler has  
completed. But it will get invoked earlier if there is a "wait ...  
with messages" or equivalent somewhere in the running handler.


local sHold

  put empty into field 1
   handlerA
end mouseUp

on handlerA
  send handlerB to me in 0 milliseconds
   put "A1" & return after field 1
   ### next line is equivalent to a libUrl blocking call

  ## this handler blocks here
  ## but handlerB will run
  put "A2" & return after field 1

Re: min() function anomalies

[Shari]

Just for fun, an alternate method which never leaves trailing commas


I must be weird in my coding or something :-)

In another project, I have a variable that is constantly changing.

I chose to add to the variable with "put something & comma after 
myVariable" rather than putting the comma first, as putting the comma 
first creates the empty place at the beginning.


Either way, the comma becomes an issue.

If I add to the variable and immediately delete the trailing comma, 
the very next handler that runs will have to check for the comma 
anyway, and add it back in when it adds to the end of the variable. 
The variable is constantly being updated, both added to and deleted 
from.


Am I the only one who has variables with commas that constantly change?

The issue also exists with trailing returns... "put something & 
return after myVariable".  But if the variable is in constant flux, 
with things being added to or deleted from, then checking for the 
comma or return becomes an issue.


Case in point, Blackjack Gold keeping track of the chips.  Chips are 
coming and going literally with every single handler.  And one 
variable keeps track of all available chips (chip objects that are 
available for use, that aren't being used in the player's chip stacks 
or bet stacks).  This variable is updated constantly, every time a 
player loses a bet, colors up or down, or every time the dealer needs 
to pay out the winners.  It always uses the first chip, deletes it, 
and adds chips to the end of the variable.  Sometimes it needs to get 
more chips if it runs out of objects, creating new chip objects and 
adding them to the end of the variable.  So it constantly creates the 
trailing comma.  But if I delete it, it must constantly check to put 
it back in if it adds chips to the end of the variable, which is 
every time the dealer wins, which of course happens a lot :-)


This doesn't have anything specifically to do with the min() 
function, but the whole issue of trailing commas wreaking havoc.

Speaking for myself, I think it's a better coding practice to avoid trailing
anything in a variable, because I wouldn't know whether the empty last item
was intentional or not.  To take your script for an example, I simply add a
line after the repeat whenever I build a list:

 repeat x
   put someNumber or someOtherThing & comma after myVariable
 end repeat
 delete last char of myVariable

I do this for any list: words, lines, etc. For me, having a delimiter at the
end of a list would be problematic.

I agree, Scott.
The only exceptions I found so far are tables and data lists that I gather
from web pages.  I need to keep a place holder so that sorting and counting
are always uniform, even if the web author decides that empty is good
enough.

This boils down to discipline and proper coding for the situation.  That
said, having code that works, then later versions of Rev spoil this in ways
you cannot predict or test, is very disconcerting.

Wasn't there something about 'cancel' and 'empty' after certain dialogs that
changed awhile back?

Re: min() function anomalies

[Brian Yennie]

Not weird at all - I think 90% of the people here (myself included)  
have usually just solved the problem by deleting the trailing comma.  
However, I can see how having multiple handlers which append data  
could confuse the issue - since non-empty lists will need the comma  
put back on before proceeding.


Although I don't exactly remember why, some odd circumstance led me  
to the habit of actually adding commas *before* items, but only if  
the content is not empty (thus my last post).


It's actually amazing how things that seem so straightforward can be  
stressed under the right circumstance.


In case it feels more logical, I suppose it could also be written:

put comma&tItem after tList
if (char 1 of tList is comma) then delete char 1 of tList

Deleting "leading" commas seems to leave your data more portable and  
predictable, however you implement it...

end AddItem


And then there's the ever so easy to use:

 put pItem into item (the number of items in pVar) + 1 of pVar

which hardly anyone uses because it's such a pain to type. But I've 
started using it again lately because if you do it that way, you don't 
have to worry about leading, trailing, or any other kinds of delimiters. 
The engine handles it all and it just works.

Re: Can I Stop Non-List Fields From Scrolling?

[Gregory Lypny]

Thank you, everyone who responded, for your advice.  It's all good  
stuff, and I'll have to start compiling a Tips file for all your  
insights.


I stumbled upon a fix, and that is to fix the line height to be  
fairly snug around the text.  For my particular fields, a 16-point  
line height for Lucida Grande 12-point works.  No more scrolling.   
(Incidentally, the default line height for a brand new text field in  
Lucida Grande 12-point is 16 points.)  Mine are all one-line, non- 
editable label fields with no space padding before or after the text,  
but they were created by duplicating other text fields that have 18- 
point line heights, and I think that extra height was the problem.


Thanks once again,

Regards,

Gregory

You can pry the documents folder from my cold dead hands! If rev 
installs any folder there i might need to look for another RAD tool, 
seriously.

Precisely my point.  You mean it works today...

Mine worked yesterday, but today it broke :-)

What if the number of items of "1,2,3,4," unexpectedly changed from 4 
to 5.

I'm a little confused here.  Is the "My Revolution Studio" folder
something that only exists for the Windows version of Revolution?

I did create the folder in my documents folder, which I still feel
should at least be an option in the installer (since it doesn't
automatically create the folder anyways).  And it does work, at least I
think it does... I'll see in the morning.


The concept itself is very good, but still needs a little fine tuning.
The better way to go would be to have a "My Revolution" folder, just in
case the developer has Studio and a beta installed, or in case they
upgrade to Enterprise and all of a suddon nothing works (which is always
a bad idea no matter how simple the fix).

It doesn't install one, but in my opinion it should. Any third-party
plugins, libraries etc should go in the "My Revolution ." folder
in your Documents folder so they are accessible when you upgrade.
Don't you remember the constant annoyance of having to manually copy
all your plugins to a new folder whenever Rev was updated? It drove me
crazy, so I am delighted with this feature, although I wish they
hadn't used the "My" :-)

I suppose they could have used the Application Support folder, but in
this case, Documents seems a better fit to me, since it is to contain
files that we have added manually, not any files that Rev puts there
automatically. Rev does not require any of these files and does not
insist that the folder be created, so if you don't like this method,
there is nothing making you use it :-)

The plugins supplied by RunRev (& presumably supported by them) are
stored in the Plugins folder in the actual Rev application folder e.g.
2.8.1-gm-1. These are always supplied with a new install, so there is
no problem about keeping them in place or up-to-date. Your own plugins
are different and so are stored differently.

And Björnke: "Please don't go - the drones need you..." - a Toy Story
quote frequently used by my children...

Cheers,

No, it is for all versions of Rev, and is intended as a place to put 
third party plugins so they will appear in the Rev IDE. The reason for 
this is that if you actually put the third party plugins into the 
plugins folder next to the Rev app, when they send out an upgrade, 
you'd have to move them from the "old" Rev to the new one. Having a 
folder outside of the Rev app area allows you to not have to go through 
this rigamarole, but Rev doesn't create this folder for you - you have 
to do it yourself based on the version of Rev you own; in your case 
it's "My Revolution Studio"; in my case it's "My Revolution Enterprise".

Re: min() function anomalies

[Jim Ault]

I use the following if the trailing delimiter is significant:

 put pItem into item (the number of items in (pVar & null)) of pVar

... of course, you could use any non-delimiter char to do this since all you
want is to make Rev think there is a char in the last "item"

But in Shari's case, there isn't any item after the last comma so she 
doesn't want to force Rev to think so. When treated as a string, Rev 
knows that a trailing comma doesn't count when itemizing lists.

This is a folder that's always been installed, before the universal folder
in Documents ever existed.  It's local to the version, so any plugins placed
there won't appear when running other versions.

You are, of  course, quite right. The usability of a function should be 
proportionate to  the required functionality. A currency formatter is not 
necessarily the same as  a thousands separator.I got carried away.

Getting carried away is a good thing, especially when osmething like
