Hi All,
  I'm having a bit of a problem making a standalone application for OS-X
from a Windows machine.  Actually making it is not the problem really,
running it is.  The save to standalone works fine and I end up with what I
am assuming is the executeable in a structure that looks as such:

My Application.app \ Contents \ MacOS \ My Application

  What seems to be the problem is the file at the end "My Application" does
not get the execute flag set on it when being transfered to the OS-X
filesystem.  My current method of transport was simply to zip the entire
directory and then unzip the file on the Mac.  This would leave the
directory structure as is, which I'm assuming is necessary.  However the
problem is the "My Application" executeable needs to have CHMOD run on it in
order to properly execute because of the execute flag missing on the OS-X
filesystem.

  Does anyone have any solution to work around this?  Is it necessary to
have some kind of "installer" program to properly set this up on the OS-X
end?  Or is there another way to handle it?  If at all possible, I would
like to be able to handle this from the Windows machine, rather than
actually needing an OS-X box.


I'd like to know the answer to this too. Has anyone else experienced this?

I'm just a simple Caveman programmer. Your advanced technology and talk 
of arrays and multiple functions frighten me. In this case, I'd just as 
soon keep thinkgs in a single handler which cavemen like me can read and

Yes, I believe they have isolated it. It took quite a while to even get 
a stack that would crash on the development machines, so it wasn't a 
universal problem for everyone. Lots of people seem to be running 2.7 
without any trouble. Eventually more data came in through tech support 
so that the team could address it. It's always a good idea to send bug 
reports to Bugzilla, and crash logs if you have them.

Agreed.

Apple stopped supporting HyperCard when? And under what OS? Yet we still see
"I have a HyperCard stack I want to convert" type questions popping up on
this list.

Sure, I'm not suggesting that you could make a living out of custom
HyperCard stacks, but I think it clearly illustrates that while software is
cheaper to buy than hardware many will keep buying software rather than
buying new hardware - until they can no longer run the software they NEED.

In my situation I'm trying to use a feature of Rev and that's not working..

Re: Acessing button scripts in a HC stack ?

2006-03-21 Thread simplsol


Hello from San Dimas,
I'm missing something here.
Why not just have Rev open the HC stack, this will convert it to a Rev 
stack? You would be able to access all of the button and field scripts 
- and do whatever you want with them. You could then write any Rev 
script needed to import/export or work with the data in what is now a 
Rev stack. This will not harm the original HC stack - as you will be 
working from a Rev-converted copy in RAM.

  Hi from Paris, 
 
I thought that I had been explicit, but apparently not ! 
 
From a Rev 2.6.1 stack, I want to open a HC stack (at the 
same time), examine it visually, type a name into a field in 
the Rev stack which corresponds to a button that I see in 
the HC stack. Then I want to hit a button in the Rev stack 
which picks up the script from that button in the HC stack, 
and returns it to the Rev stack where I can play with it, using 
a Rev script. 
 
I also want to do the same with scripts from fields.

Please don't ask me why I don't use "Cut" and "Paste" . 
 
All of this is with the object of automating (as far as I can) 
my HC to Rev conversions. Building the stacks is a piece 
of cake with Rev, but modifying the scripts is a pain, so I do 
it .. using a script . of course ! My problem is bringing 
the script over to Rev .

The tabstops are a cumulative number representing the pixels from the
left of the field for each stop. If you set them to "120,125" the
first column will be 120 pixels wide and all other columns will be 5
pixels wide.

I recommend Frederic Rinaldi's revTabRuler plugin which now comes as
one the the standard plugins in your Rev installation. It allows you
to set tabStops graphically by dragging  them along in his palette. I
wrote an article about it some time ago for revJournal
. Just ignore the
installation instructions as it should already be in the plugins menu.

All newly imported HC stacks have their HCAddressing property set to 
true. That means you must reference the button, or any other object, 
just as HC does. If you say "button 1" then Rev will assume the button 
is a card button. If you want to specify a background button you must 
reference it as "bg btn 1". Same for fields: "fld 1" means a background 
field, and if you want to refer to a card field, you must specify "cd 
fld 1".


If you set the HCAddressing of the stack to false, after that you can 
refer to the objects in the Revolution way, without specifying "card" or 
"background".


Another thing that may be happening is that when you click on the Rev 
stack, your scripts will try to find "button 1" in the Rev stack. 
Instead, you must specify the stack:


  get the script of bg btn 1 of this cd of stack "myImportStack"

Another way to do the same thing is to set the defaultstack:

  set the defaultstack to "myImportStack"
  get the script of bg btn 1 of this cd



Please don't ask me why I don't use "Cut" and "Paste" .


I won't, though it would probably be easier. But I do wonder why you 
don't just use the imported stack. Why move everything? I have converted 
more HC stacks than probably anyone (it's a lot of what my company does) 
and I have never had to rebuild a HC stack from scratch.

Thanks for explaining further, now I hope I understand and I think I
have the solution :-)

When you open a HyperCard stack in Rev, the property called
"HCaddressing" is set to true. This means that cards & fields are
referred to as "card fields", "bg fields", "card buttons" & "bg
buttons". As in HyperCard, the default is for fields to be background
fields and buttons to be card buttons.

If you are just trying to access them using "field" or "button", it
will work for some but not for all. Your importer script needs to work
out whether the object is a card or background object and address it
accordingly.

Sarah

It is so :-(
I found the best compromise was to put the most important search items
as attributes, instead of elements. You can search by attribute.

However I agree, it seems to be an obvious missing feature that should
be part of the library.

Acessing button scripts in a HC stack ?

2006-03-21 Thread Francis Nugent Dixon


Hi from Paris,

I thought that I had been explicit, but apparently not !

From a Rev 2.6.1 stack, I want to open a HC stack (at the
same time), examine it visually, type a name into a field in
the Rev stack which corresponds to a button that I see in
the HC stack. Then I want to hit a button in the Rev stack
which picks up the script from that button in the HC stack,
and returns it to the Rev stack where I can play with it, using
a Rev script.

I also want to do the same with scripts from fields.

"Reasonable request - no other interest"
 (Only the very best - Tycoon - 1992 - Peter Kingsbery)

Please don't ask me why I don't use "Cut" and "Paste" .

All of this is with the object of automating (as far as I can)
my HC to Rev conversions. Building the stacks is a piece
of cake with Rev, but modifying the scripts is a pain, so I do
it .. using a script . of course ! My problem is bringing
the script over to Rev .

Hi Devin,

You need to escape ", ', <, and < when entering data into an XML 
node.  I can't remember if RevXML has any handlers for this or if 
you just have to do it by hand.  For an example of the escape 
characters just do a Google search for "xml escape characters".


You may want to check out Ken Ray's XML library.  I haven't used it 
but browsing through the API, there is a stsXML_replaceEntities that 
looks like it would do what you want.

As I recall, when the possibilty of encrypting custom props along with 
scripts was brought up on the improve-rev list, it was shot down because 
it would kill access to those properties.


Fortunately a quick test here confirms what you've found: custom props 
are indeed encrypted when the password is set, but only on disk -- you 
can still view and edit the data from scripts, such as the IDE's.


So while it keeps people who don't have Rev from extracting data, it 
still leaves data vulnerable to those who do.


Isn't there a BZ request for SC-style password protection?  In SC 
setting the password prevents the stack from being opened in the IDE. 
If there isn't already a request for this maybe someone should post one, 
with recommendations on what that password property should be called.

Re: Making the move...

2006-03-21 Thread Rob Cozens


Hi Geoff ,


Wow -- so what does this do?



From Serendipity Reference:

>>

The findSDBRecord command checks for the existence & locked/unlocked 
status of a record with the record type and key specified in line 1 of 
sdbBuffer.  It can also be used to unlock a record that was previously 
locked but not changed or to return a count of the number of records 
with certain field contents.


findSDBRecord is undoubtedly the most complex, but also the most 
powerful, SDB command.  It is the only SDB command that will retrieve 
information from multiple records in a single call.  As such, it is 
ideally suited to retrieve specified fields from a range of records for 
reporting or analysis.


exactKey (boolean) defaults to true, in which case findSDBRecord 
returns card id "0" if the exact key is not in the database; otherwise 
findSDBRecord will return the id for the record with the closest higher 
key of the specified record type.


If fieldDelimiter is empty findSDBRecord simply returns the Revolution 
card id of the record in word 4 of the result.  If fieldDelimiter is 
not empty, itemList contains a list of field references (one per line) 
to retrieve.  A field reference can take two forms:


* a number that resolves to the field's ordinal position in the record 
(0 = the record key)
* an SDB field reference ([Record Type]&":"&[dataname]), which the SDB 
handlers will resolve to a field ordinal.


These two forms of reference can be used interchangably EXCEPT for 
record types that have no Dictionary definition in the database.


findSDBRecord then puts a delimited list of the contents of the fields 
into lines 2 to -1 of sdbBuffer.


setPosition (boolean)  defaults to true.

unlockRecord (boolean) defaults to false.  If true and the record was 
locked by this user, it will be removed from the locked record table.


findSDBRecord can be passed search criteria that must be met before a 
record is retrieved, and instructed to search forward or backward from 
the key if the key's record does not meet the search criteria until the 
first acceptable record is found.


searchForward (boolean) determines search direction; default is true 
(forward).


searchCriteria contains one or more lines in the following format:
-- field reference,test,target,and/or
* field reference is the field's ordinal or Data Dictionary name, as 
defibed above.

* tests: "=" ,"<>" ,"in", "not in", "<", ">", "<=", or ">="
* target is the result to which the item is to be compared; it must be 
a value, not a reference to another field in the record

* "and" or "or" is not needed on last line of search criteria

Example search criteria (assumes the field is defined in Record Type, 
"TYPE" as dataname "department"):

"TYPE:department",>,21,and
"TYPE:department",<,34
Selects only records where the value of field "department" is between 
22 and 33.


If cutoffKey is not empty, findSDBRecord will discontinue the search 
when it encounters a record with a key > cutoffKey if searching forward 
or < cutoffKey if searching backward; otherwise the search will end 
with the first matching record if recordDelimiter is empty or the 
last/first record if it is not.


If recordDelimiter is empty, findSDBRecord returns information for the 
first matching record it encounters.  If recordDelimiter is not empty, 
findSDBRecord puts empty into sdbBuffer and returns the number of 
records matching the search criteria in word four of the rersult if the 
fieldDelimiter is empty; otherwise it returns the information for each 
matching record found between the key passed in sdbBuffer and cutoffKey 
or the last/first record of the specified record type.  This 
information will be found in lines 2 to -1 of sdbBuffer.  (The 
recordDelimiter is used to delimit individual records.)


Note that findSDBRecord will return a locked record error if the record 
exists but is locked by another user.

One thing you might want to consider is putting the image data into fields
as opposed to custom properties, the reason being that field contents are
encrypted along with the rest of the stack data when a stack is password
protected, while custom props are not.  You can still display images from
the fields' contents, and the fields themselves cannot be cut and pasted.

I don't know who you audience is but I would guess the likelihood of your
users owning a copy of Rev is lower than folks' ability to snoop around file
contents.

That was it. I had put a block comment in the middle of the script.

I'd like support this point. :-)

It is impossible forever try support old, dead, dying versions of OS.

Apple itself have stop support OS9.
Microsoft have stop support even Win98 if I not mistaken.

I can understand if you support already existed app,
But develop new app for old hardware/OS is not best idea.

Forcing customers to upgrade old MACs you help Apple also :-)

You help self as developer, because it is dream for a developer to trash
this Zoo with Classic, Carbon, ... support, and leave only with OS X MACHO
version on MAC,and only Win XP version on Windows with their modern

Actually, you can *retrieve* CDATA with revXMLNodeContents, but you can't

No need, Klaus - the Basic version of the Library will do the finding for

Re: Combined Events

Why are you using "theButton" as a parameter?

First, where is the mouseDown handler?

In the message path, it should be either
in the button or field the user clicks
or in the card, stack, or back script behind the button or field.

If the mouseDown handler is in the button or field, use
on mouseDown
since the button clicked is known.

If the mouseDown handler is in the card or stack script then use

on mouseDown
   answer the target
   if the target contains "button 1 " then
  -- a button was clicked and its number is 1
  ...do this
   end if

Mac OS-X standalone from Windows machine

2006-03-21 Thread Levi Kendall

Hi All,
  I'm having a bit of a problem making a standalone application for OS-X
from a Windows machine.  Actually making it is not the problem really,
running it is.  The save to standalone works fine and I end up with what I
am assuming is the executeable in a structure that looks as such:

My Application.app \ Contents \ MacOS \ My Application

  What seems to be the problem is the file at the end "My Application" does
not get the execute flag set on it when being transfered to the OS-X
filesystem.  My current method of transport was simply to zip the entire
directory and then unzip the file on the Mac.  This would leave the
directory structure as is, which I'm assuming is necessary.  However the
problem is the "My Application" executeable needs to have CHMOD run on it in
order to properly execute because of the execute flag missing on the OS-X
filesystem.

  Does anyone have any solution to work around this?  Is it necessary to
have some kind of "installer" program to properly set this up on the OS-X
end?  Or is there another way to handle it?  If at all possible, I would
like to be able to handle this from the Windows machine, rather than
actually needing an OS-X box.

Re: Tabbed group background thingies

2006-03-21 Thread Dan Shafer

Probably you're just missing hide/show commands. That's the "trick" in
tabbed designs. Depending on how you've managed the tabs, you may need to do
that explicitly.

Check out the great tutorial at

Ken,

This is good to know.  The RevXML external doesn't handle CDATA, does  
it?  I seem to recall that when I tested using CDATA with RevXML it  
didn't work which is kind of a bummer.

Yes. You need to use a CDATA node instead of a normal element node. The
markup looks like this:

You can put anything into a CDATA node - it's ignored by the parser. My XML
Library handles getting and setting CDATA information for a node quite
easily - if your XML looked like this:

You could get the data with:

  put stsXML_GetNodeData("/root/myHTML") into tHTML

and set it with stsXML_SetNodeData.

By keeping it as CDATA you don't need to replace characters to get what you
want...

Tabbed group background thingies

2006-03-21 Thread Andy Calloway

Having read a bit of Dan's book and gone through a couple of the RunRev
demos, I thought I'd try to apply what I'd just learned so I went back to a
stack with tabs on it. It's got three tabs and I've added some text fields,
buttons etc to some of them. It worked fine, click on a tab and the new
objects leap into view.
 
Then I got too cocky and added another tab between the first and second one.
Now, when I click on it, the items from the previous selected tab remain in
place where I would really expect it to be blank.
 
Have I missed something here?

Re: [?] Mac Classic, 2.6.1, MySQL

2006-03-21 Thread simplsol


Sean,
Permit me an "off the wall" question...
Do you REALLY need to support OS 9?
Any computer Apple has made since 1998 (8 years!) will run some flavor 
of OS X (although they probably need more RAM). The time and effort you 
would put into supporting OS 9 could be invested in making your OS X 
product even better - giving your customers another reason to make the 
move. OS 9 is dead, or at least dying, first there were new computers 
that would not boot into 9, then there were new computers that wouldn't 
run 9; as used and reburb computers run out there will be no OS 9 
options for your customers.
We had originally intended to port our HC business system to Rev in OS 
9 and OS X. Then we decided that the customers running OS 9 had a good 
business system they could continue to use (our current HC one). New 
customers and all current customers moving to OS X would not care about 
OS 9 compatibility.

Your situation may be different.
Just a thought.

Database Conversion

2006-03-21 Thread Robert Sneidar

Does anyone know of any good dBase/Foxpro table to sql/Valentina  
conversion utilities? I can write one in Revolution I suppose, but I  
would have a lot of front end work to do first, and this project is  
already huge.

Re: use-revolution Digest, Vol 30, Issue 54

2006-03-21 Thread Robert Sneidar

Wow thanks Sarah that is huge! I didn't see that anywhere in the docs  
but I probably didn't look closely enough.


But no I have an odd thing happenning. I can only set columns widths  
up to 120. Anything over is interpreted as width-120 so that if I set  
the width to 125 I get a column 5 pixels wide. Odd huh? There is  
probably a max width for the columns property I need to set. I will  
dig around. I am going to have to get used to that again.


Viva le Hyperca... err  REVOLUTION!

If you don't need the fields to vary once set, you can just use the
tabStops, e.g.
  set the tabStops of fld "MyList" to "100,150,300,320,400"
will produce columns with widths 100, 50, 150, 20 and 80 with all
extra columns also being width 80.

If you need the column widths to be variable, then you need Chipp's
altFldHeader plugin which you can get from here:

Follow the links to altPlugins -> Downloads and you'll find it near
the bottom of the page.

Cheers,
Sarah

Re: linux sound issues

2006-03-21 Thread Girard Damien


Hi joe,

The media support under runrev under Linux/Unix is really poor (compared  
to Windows or MacOS X).


There is a enchancement request about that, please vote for him :

http://support.runrev.com/bugdatabase/show_bug.cgi?id=2290

--
You will cannot play a video file in your stack with your trick, If you  
want
an audio support, you will have to write some scripts and to manually call  
mplayer.


And you cannot create a plugins for Revolution in C++, because the  
Revolution Linux/Unix

engine doesn't support that (compared to Windows or MacOS X).

Hi Devin,

You need to escape ", ', <, and < when entering data into an XML  
node.  I can't remember if RevXML has any handlers for this or if  
you just have to do it by hand.  For an example of the escape  
characters just do a Google search for "xml escape characters".


You may want to check out Ken Ray's XML library.  I haven't used it  
but browsing through the API, there is a stsXML_replaceEntities  
that looks like it would do what you want.


Thanks Trevor. I already knew that I had to escape those characters,  
plus '&' when writing xml. You triggered a "Duh!" moment in my brain,  
as it dawned on me that I'd also have to escape those other  
characters in my html markup.


It's working now.

Re: Table Column Widths

2006-03-21 Thread Jonathan Lynch

Another option:

If you are using the table as a user interface, then I have a pseudo table
object that acts like a table should. It allows you to move columns and
rows, and resize columns, and insert and delete rows and columns, etc...

It can be found here:

http://revolution.widged.com/stacks/


(thanks to Marielle)

I would not use the pseudo table for mass data storage, because there is a
lot of memory usage and scripting involved in making the separate fields at
like fields in a table.

This is true, but passing by reference doesn't violate this,  
depending on how it's used. If you have a clear-cut function that  
operates on a value passed by reference because of its size, that's  
not a bad thing I don't think.

Application Browser Anomaly

2006-03-21 Thread Rob Cozens


Hi All,

Rev 2.7; WinXP TPC 2005 Edition:

Both last night and now this morning I have done something that sets 
the Application Browser in a state such that double-clicking on a 
substack opens the script of the substack instead of opening the 
substack itself and double-clicking on a card of an unopened subStack 
opens the script of that card..


Last night I tried shutting down RR and restarting it without 
rebooting, but the problem was still there when I turned the computer 
off for the night.  This AM, double-clicking on any substack shown in 
the AB worked...for a while, then I found myself back opening scripts 
instead of opening substacks.  This time restarting RR solved the 
problem; but for how long?


Has anyone else experienced this?  Ideas, anyone?

I will note one possible issue:

The subStack I'm attempting to modify is Serendipity Library's 
"sdbDictionary."  At runtime it's opened as a modal dialog by the SDB 
Tools plugin, and it needs the initialization in SDB Tools to open 
correctly [there are issues with opening it directly from Serendipity 
Library, even with messages locked].  When opened this way, the AB 
shows sdbDictionary as a subStack of SDB Tools instead of Serendipity 
Library.


The problem is in editing a stack open in modal mode [BTW, debugging in 
modal stacks causes problems too--or at least it did in earlier Rev 
revs].  So my practice is to open sdbDictionary modally with SDB Tools, 
close it, open Serendipity Library, open the AB [where sdbDictionary is 
now listed as a subStack of both SDB Tools and Serendipity Library], 
and double-click on the subStack or one of its cards to open it for 
modification.


I have used this technique for a couple of years with earlier revs and 
not encountered a state where the AB opened the script of a subStack 
instead of the stack itself.  Could the problem lie here?

You suspected correctly, Alex.  Thanks for finding another mistake.  That
example only shows that the list of tokens is insufficient to reproduce the
_appearance_ of the handler.

Despite that weak example, the point was that the list of tokens is
insufficient to reproduce the _semantics_ of the handler, and therefore not
useful to "get a handler from a script."  Here's a better-chosen example of
two handlers with different semantics but the same tokens for the bodies of
the handlers:

 


But the interesting thing is that if you do something like
  token K1 to K2 of someScript
then it gives you the complete text between the char position of token 
K1 and the char position of token K2


I've uploaded a stack to revonline (username alextweedly, name 
FindHandler, category programming) which does this.
Moderately tested  but not thoroughly. (btw - only for handlers - 
extension to functions, setprop, etc.. is easy)


The essence of the (short) version is



function findhandler pScript, pHandler
put 0 into tStart
put 0 into tEnd
put 0 into i
put token 1 to -1 of pScript into pScript
repeat for each token t in pScript
add 1 to i
if t = "on" then
if token i+1 of pScript = pHandler then
put i into tStart
end if
end if
if t = "end" then
if token i+1 of pScript = pHandler then
put i into tEnd
if tStart > 0 then exit repeat
end if
end if
end repeat
if tStart = 0 or tEnd = 0 then  return ""

-- to simply return the handler text

return token tStart to tEnd+1 of pScript

end findhandler


Note that this fails to return any closing, trailing comment. For 
example, if the last line had been



   end findhandler-- end of function to do something


it would not have included the comment.

The stack includes another version which returns the line numbers of the 
start and end lines of the handler, and therefore allows you to include 
such trailing comments. It does not handle trailing, multi-line, block 
comments :-( but I'd regard a format like


  


end findhandler   /* some comment

  in here */


as particularly bad style.


NB This is still only a 99.99% solution. It will fail in the case where 
there is a multi-line block comment which includes a complete, EXACT 
copy of the handler being sought, and which precedes the handler in 
question. Since it must be an exact copy, then if you use this to 
duplicate the handler somewhere else, it will give the correct result 
anyway :-)

This style of commenting shows rev's inability to parse for handler  
names there after.

Have a look at the handler list field of the revscripteditor.
Take a multi handler script and comment the second handler like  
mentioned by Geoff above.
On reopening the same script in the editor, only the first handler  
will show in the handler list field.

Has anyone got any thoughts on building a help file for an application ?

I am considering making a pdf file using openoffice, which can build
in hyperlinks and bookmarks.  But I think the searching features
offered by traditional help files may be easier on the user.  The help
file will be medium sized, say 40-50 pages.

HTML tags in XML

2006-03-21 Thread Devin Asay


Hi Folks,

Is it possible to store html styled text in an xml document and then  
successfully retrieve the text with html markup intact?


I'm working on an application where I need to save styled text in an  
XML document. I can successfully insert the htmlText of the styled  
field into the xml document so I end up with a node that looks like  
this:



Here are my comments.
Some of the text is colored red &  
blue



However, when I read this node in with the revXMLNodeContents()  
function the html tags are stripped out and all I get is naked text.  
Here's a code snippet:


put revXMLNodeContents(vSessionTreeID,vCurrentComment) into  
tCommentTxt
set the htmlText of fld "comments" of cd theCard of stack  
"ClipData" to tCommentTxt


When I examine the tCommentTxt variable in the variable watcher I see:

Here are my comments.
Some of the text is colored red & blue

Notice that it correctly rendered the ampersand entity. But the  
formatting is gone.


Is there a way to do this? Will I have to resort to saving the  
RTFtext in the xml node or something like that?

Thanks for the link, Jim. I was in the process of putting together a 
list of features and functions for an introductory scripting language to 
be implemented in Revolution, and NetLogo will definitely help clarify 
my thinking.

This would be very nice.  I could have used this when I was a teacher. 
 I'll be using it with my son soon.

Re: Get a handler from a script

You suspected correctly, Alex.  Thanks for finding another mistake.  That
example only shows that the list of tokens is insufficient to reproduce the
_appearance_ of the handler.

Despite that weak example, the point was that the list of tokens is
insufficient to reproduce the _semantics_ of the handler, and therefore not
useful to "get a handler from a script."  Here's a better-chosen example of
two handlers with different semantics but the same tokens for the bodies of
the handlers:

on a
  put "foo" into bar
  return bar
end a

on b
  put "foo" into bar
  return "bar"
end b

I'm looking forward to it.

If you don't need the fields to vary once set, you can just use the
tabStops, e.g.
  set the tabStops of fld "MyList" to "100,150,300,320,400"
will produce columns with widths 100, 50, 150, 20 and 80 with all
extra columns also being width 80.

If you need the column widths to be variable, then you need Chipp's
altFldHeader plugin which you can get from here:

Follow the links to altPlugins -> Downloads and you'll find it near
the bottom of the page.

Sarah

Are you opening the HyperCard stacks in Rev? If so, you should read
Jacque's excellent tutorial on the subject at
.

Apart from that, I don't understand what you mean. Are you saying that
imported stacks don't have their buttons, or that the imported buttons
don't have scripts or what?

As a general rule, I recommend creating a new stack in Rev and copying
the scripts over with the necessary changes, instead of importing
directly, but I have had no major problems with either method.

Sarah

Re: Help with Arrays??

Here's the code that works just fine. Please note that I've  
confirmed the value of x, it is not the problem here. The function  
returns an Array.


   put MyFunc( x ) into theArray
   DisplayPurchaseLine x, theArray

The following code fails miserably passing empty for theArray  
argument; x is passed in just fine:


   DisplayPurchaseLine x, MyFunc( x )

Why do  I need to put the MyFunc() return value (an array) into a  
local variable first. It clearly makes it out of the function  
call, but cannot then immediately be used as a parameter. Huh?
