We (TAB of NSW as it was then) had a pair of these old dears(360/44s, that is). We actually had the 'Commercial Feature" which gave you LM/STM, BXLE and BXH implemented in hardware, but the storage-to-torage and packed decimal instructions were all emulated (slowly!) via an IBM supplied program ( the emulator deck) which was a stand alone program you had to ipl into extension storage. We were not allowed to use these instruction in our online system, (not surprisingly!)

Except for the LM/STM/BXLE/BXH and Commercial Feature, it was a hardware-based instruction set. Implementation of the Commercial Feature was, and is, a whole different discussion. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ******************************************************* PLEASE NOTE: This internet email message has been checked for viruses and appropriate content to ensure it complies with TABCORP's electronic communication policy. ******************************************************* *********************************************************************************** The information in this e-mail message and any files transmitted with it are intended to be confidential and for the use of only the individual or entity to whom they are addressed.
