Re: [U2] XPath queries
Yuck! That sounds like a bug to me. Anywhere else, the quotes would be
mandatory.
Always glad to help!
Default namespaces have always felt like a bad compromise to me...

Subject: Re: [U2] XPath queries
Thanks Robert and Brian,
As you pointed out, having a default namespace was the issue. However it took
me awhile to work out that the nsMap parameter of the Locate statement can't
have quotes around the uri. Once I had (accidently) discovered that, the
xdomlocate function worked.
include UNIVERSE.INCLUDE XML.H
xml = '?xml version=1.0 ?'
xml := 'ABRPayloadSearchResults xmlns=http://tempuri; '
xml := 'response'
xml := 'exceptionException Message/exception'
xml := '/response'
xml := '/ABRPayloadSearchResults'
* !! nsmap = 'xmlns:a=http://tempuri;' Does Not Work with quoted uri !!
nsmap = 'xmlns:a=http://tempuri'
xpathStr = '/a:ABRPayloadSearchResults/a:response/a:exception'
if xdomopen(xml,XML.FROM.STRING,hd) # XML.ERROR then
if xdomlocate(hd,xpathStr,nsmap,hn) # XML.ERROR then
if not(xdomgetnodename(hn,name)) and name[9] = 'exception' then
crt 'Located ':name
end
end
end
Many thanks,
Stuart Boydell

Beware of default namespaces. If you have one defined, then XPath needs to have
a namespace mapped to a dummy prefix, and you have to qualify the prefix. The
following can be referenced using /x/y.
xysomething...
But this has a problem:
x xmlns=fooysomething...
Internally, XML tracks this like /{foo}:x/{foo}:y. What you have to do is
tell the XPath processor to map some prefix, say 'a' to the namespace 'foo',
then use /a:x/a:y.

[U2] SB Dict with User Subroutine and TCL
I need help building a SB Dict that calls a User Subroutine with several arguments. This needs to work from both within SB screens and from TCL. Originally, I have a derived field defined as: (B(SYSS9075.1,'VIA',SHIP_VIA)) where SYSS9075.1 had three arguments, 'VIA' was hard coded and SHIP_VIA was whatever value was in that field (in this case, field 10). This worked fine from TCL, but SB was blowing up with an error about incorrect number of arguments (and would likely not have a clue what SHIP_VIA meant). I then tried: (B(SYSS9075.1,'VIA','10')) where SYSS9075.1 had no arguments, and extract the info from PARAMS.

[U2] Different Number of Arguments Error

barcode printing. I needed to make two changes. One was the name
change to fit within our naming convention and the other was the name of
a the variable VALUE because it's a reserved word in System Builder.
So I have this statement:CALL SB.PROCESS('SYS9008,0\1\0\110022')
It's calling a basic subroutine whose first line is this:
SUBROUTINE SYSS9008.1 (WIDTH, HEIGHT, ORIEN, MYDATA)
I'm getting this error: In
..\..\..\FLOPROGS\DEV\DEV.IIBASE8\BP8.0\_SYSS9008.1 at line 141 Error,
SUBROUTINE 'SYSS9008.1' has different number of arguments than its CALL
statement.
It never gets to 141. I put display statments early on in the program
to display WIDTH, HEIGHT, ORIEN AND MYDATA. It doesn't even get to that
point.
I count the number of variables the subroutine wants and I count the
number I'm passing and, to me, they appear to be the same. What am I
missing?

Re: [U2] OPENSEQ and Abnormal termination of UV
If your file is opened, then comparing it to an empty string is what will cause an invalid data type error. WHY!!! If the datatypes don't match, then the result of the comparison is FALSE, not INVALID. It is logically correct to do such a comparison. The result I am looking for is the logically correct response. It SHOULD NOT crash the program! And it worked fine on INFORMATION, why not UV? It is a bad idea to allow it, it encourages bad programming practices and it can hide a bug in your program for example if you do: READ CAR FROM CARS ELSE CAR = '' IF CARS # '' THEN Here what was intended was to compare CAR to '' not CARS but having the S there is a typo. If we don't allow datatypes of different types being compared this bug has a greater chance of getting caught during development because the program will fail on comparing the file to a null string. If you use FILEINFO it shows that you know that the variable you are testing is a file. I've seen a similar case where a subroutine was expecting: SUBROUTINE ABC (MAT A, MAT B, MAT C) A programmer only needed the contents of the matrix B and C to call it and did: CALL ABC(,MAT B, MAT C) Only thing Matrix ABC puts something in MAT A and since the programmer passed an empty string what happens is that the content of Matrix B is over-written causing data corruption. It would probably have been a good idea to detect that since a Matrix was expected, it shouldn't be legal to pass a dynamic array to the subroutine. Most modern OOP programming languages don't allow for types of different kinds to be compared to one another without some way of casting them. ___ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
Re: [U2] SB Dict with User Subroutine and TCL

Re: [U2] OPENSEQ and Abnormal termination of UV
I know what you're saying, but just to make sure we're precise I'll add a footnote. The run-time machine doesn't have to find additional memory *each* time you add to a dynamic array (as you said perhaps just imprecisely). Rather, your workspace arrays have certain fixed sizes and it's only when you go over this size that it will allocate you a new larger area and move the array there. So for example, you get slots that are 50 bytes, 250 bytes, and so on, probably implementation dependent. The run-time machine will allocate you a smaller area at first, until it knows you need a bigger one. Alternatively, garbage collection will return to the available pool, the no longer used space for arrays that have shrunk. I never did any testing to see if the garbage collector actually works *while* your program is running or only after the signal that the program is now finished. I do agree however with the observation that reading a large amount of data into a dynamic array is *most likely* causing the run-time machine to allocate you the entire size of that data in your own *workspace*.

I remember many years ago (I won't say how many) when we were on much slower hardware, explaining to a coworker that it was better to use dimensioned arrays when possible because they were faster to populate than dynamic arrays. The reason they're faster is because the necessary space for them is already reserved in memory. A dynamic array has to go out and find add'l memory each time you add to it. Looks like putting a sequential file in a dimensioned array makes it go out and reserve a block of memory the size of the entire file. If that's the case then making FILEVARS a dynamic array *should* work. -John -Original Message- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of John Hester Sent: Tuesday, May 18, 2010 11:42 AM To: U2 Users List Subject: Re: [U2] OPENSEQ and Abnormal termination of UV Yes, I see your point. I wonder if the integer gets treated like a string in the first instance. I wonder what the result with FILEVARS1 would be. -John -Original Message- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Anthony W.

What I think OPENSEQ is doing is keeping track of the position where the EOF mark is so it will know when the end of the file is reached. For a file greater than 2GB in size, this position is an integer that takes more than 32 bits to store. UV, being a 32-bit application, is not going to be able to handle it. The maximum positive integer value a 32-bit application can reference is 2147483647. The problem is, FV.FILE and FILEVARS(1) are *allegedly* *functionally* *identical*. An element of a dimensioned array, is supposed to be a normal variable in every way shape or form. The problem is that, in this instance, it clearly isn't because the variable works while the element (allegedly identical) causes a crash. I'd agree with Perry.

...That's what I absolutely HATE about artificial stupidity. It thinks it knows better than me, and gives me what it thinks I should have, not what I asked for. Then again, I can't imagine it thinks it should CRASH! :-o Bill Anthony W.
