VDEFINE errors are restricted to languages that use VDEFINE. Rexx is not one of those. You are "probably" immune. I say probably because I can't envisage a situation where you wouldn't be but then I'm not all-seeing oracle.
For an assembler/PLI/COBOL routine the likely bad thing would be ISPV006. LINENUM - It hasn't changed nor was an alternate value made available. And it's 6-bytes not 4. Or maybe 7-bytes. "For compatibility with previous releases of ISPF, a length of 6 or 7 is allowed in cases where no data loss will occur." Weird. I don't have any info about why LINENUM and ZSCROLLN are different in the way they are. -Hank ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
