These suggestions are wrong in so many ways. RFE should only be suggested when it's useful and changing len has never been a solution for distinguishing between implementations. I've never seen a valid use case for S-CONS. First, passing register number is useless at runtime. Second, offset has been available since the begining of IBM ASM (e.g L R1,PSATOLD-PSA(0), DC AL2(PSATOLD-PSA), ...). This is most likely what Binyamin wants. Third, I'm guessing a long SCON will match the instruction format (low high). If you truly require a long S-CON, then it will be documented in HLASM REF in the S-CON section. Since all long instructions use Y (e.g. LA versus LAY), then my guess would be SY(xxx) if IBM implemented it. As for an RFE, forget about it because if you find a valid use case, then it will be extremely obscure. E.g. abend recovery. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
