What was OS/VS2 without MVS? To me: OS/VS1 means a single large (up to 24-bit address limit) address space. MVS means multiple address spaces, (each up to 24-bit address limit). How does OS/VS2 before MVS fit in this picture? >See >http://bitsavers.trailing-edge.com/pdf/ibm/370/OS_VS2/Release_2_1973/GC28-0667-1_OS_VS2_Planning_Guide_for_Release_2_Nov73.pdf > -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
