RPGLE PARM limit

[tfass]

I have converted an RPG/400 program to RPGLE because I was getting the error 'too many parm operations for the specified CALL' on the compile and confirmed the limit was 255 for PARM statements for a PLIST. After converting to RPGLE, I expected this would now compile because all documention I can find says that a PLIST can have 399 PARM stmts. I have 256 and am still getting the RNF0650 error. Is there something else I need to look for in the program and/or change?

Thanks for any help.

Did you change the source member type to RPGLE?

 

[tfass]

Yes. FYI, I used the CVTRPGSRC command and it converted the program fine with only a few minor tweaks needed.

Found it. You are limited to 255 unless you are using CALLB. See the text from the manual below:

One PARM statement, or as many as 255 for a CALL or 399 for a CALLB or PLIST are allowed.

Thanks. I had found that text in the manual but I guess I misunderstood it as "399 for a PLIST" (reading it as PLIST independently used and not part of the CALLB) and was allowed thinking they meant:

CALL PGM PLIST1

PLIST1 PLIST
PARM P1
...
PARM P366

as opposed to:
CALL PGM
PARM P1
...
PARM P255

Thanks for your help.

tfass -
You might think of using the Local Data Area to transfer data back and forth to/from programs. We use CopyBooks to keep them equal. Quick, Clean, Easy - IMHO!

IIRC, the max size of the LDA is 1,024 bytes. If all 256 parms fit within that size, the LDA may be the ticket.

You can pass a PLIST thru a SPECIAL device. Never done that. But it's on the internet, therefore it has to be true.

http://publib.boulder.ibm.com/infocenter/iseries/v5r4/topic/books/c0918160.pdf

* SPECIAL file with PLIST operation: Allows you to specify an input/output
device that is not directly supported by the RPG/400 programming language.
You can add additional parameters to the RPG/400-created parameter list with
the use of the PLIST and PARM operation codes.See “Special File” on page 101 for information on the SPECIAL device.
