Re: Subfield lenght cannot exceed 256 bytes

["Scott Klement" <infosys@xxxxxxxxxxxx>]

Hi,
     First, I'd like to say (just to get it out of the way) that the
silly 256-max length restriction was removed in RPG IV (ILE RPG/400)
and unless its NOT an option, I'd strongly suggest using RPG IV, its
a far more robust language.

Assuming that you can't use RPG IV:

Although a single field's length is limited to 256, data structures
and arrays are not.  This provides with some simple workarounds to
your problem.

You did not mention WHY you're using a data structure.  Depending on
what else you're doing with the data structure, you can simply define
multiple subfields in the DS, like so:

     ** Example for a 400 byte record length:
     IDSREC       DS
     I                                        1 256 PART1
     I                                      257 400 PART2
     .... then later in the program ...
     C                     CALL 'MYPGM'
     C                     PARM           DSREC

If for some reason, you can't do it that way, another method is to
use an array instead of a data structure:
     E                    REC       400  1
     I            DS
     I                                        1 400 REC
     .... then later in the program ...
     C                     CALL 'MYPGM'
     C                     PARM           REC


Good Luck...
