Re: Quick RPG String Question

[Mel Rothman <mel@xxxxxxxxxxxxxx>]

ILE RPG for AS/400 Reference Appendix A. RPG Restrictions show maximum character 
fields as follows:

V4R2: 32767 bytes
http://publib.boulder.ibm.com/pubs/pdfs/as400/V4R2PDF/qb3agz00.pdf

V4R4: 65535 bytes
http://publib.boulder.ibm.com/pubs/pdfs/as400/V4R4PDF/QB3AGZ03.PDF

Clearly, 65535 byte character fields were fully documented in V4R4.

I would trust Barbara Morris when she says 65535 character fields were PTFd to 
V4R2, but that's a moot point for you since you are interested only in V4R5 and 
later.

I compiled the following on a V5R2 machine with target release V4R5M0.  It ran 
correctly on the V5R2 machine (I don't have a V4R5M0 machine to test on).

H dftactgrp(*NO) actgrp(*new) option(*srcstmt : *nodebugio)
D big             s          65535    varying
C                   eval      big = *all'X'
C                   eval      *inlr = *on
C                   return
