Have a look at the "Language Environment Programming Guide for 64-bit Virtual Addressing Mode" manual, chapter "Chapter 21. Assembler considerations". It has some description about AMODE 64 assembler. I browsed it quickly, only. It talks about XPLINK convention to be a prerequisite for AMODE 64 assembler in a LE supported way. I never did anything with XPLINK, so I cannot say how much effort this is, but maybe you can change your assembler code to be LE AMODE 64 compatible. While your "SDWA hack" seems to work (today), it is cheating, as you said yourself. May hurt you, or your customer in the future. -- Peter Hunkeler ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
