Hopefully.. BAL/BALR will still be around.. It's been around since S/360 and it's here to stay. That's the power of the architecture.. Please.. find *ONE* single architecture that's still capable of running programs written 45 years ago ! <SNIP> Discussed this very thing with a person who used to work on Burroughs systems. Seems that UNISYS systems that are patterned after the Burroughs machines are able to run programs that old. Not sure about the UNIVAC side of the house. Seems that the BUNCH had a common idea at some point of protecting the investment that their clients made in software. (BUNCH - Burroughs Univac Ncr Cdc Honeywell -- if I remember correctly). Regards, Steve Thompson PS. BAS and BASR were implemented on the S/360-20. Because it only had 16 bit registers, not the full 32 of its bigger siblings. -- Opinions posted by this poster may not be those of poster's employer. -- ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
