OS/VS1 did http://bitsavers.trailing-edge.com/pdf/ibm/370/OS_VS1/GC20-1752-0_OS_VS1_Features_Supplement_Aug72.pdf OS/VS2, release 1 (SVS) used 4K pages http://bitsavers.trailing-edge.com/pdf/ibm/370/OS_VS2/Release_1_1972/GC20-1753-0_OS_VS2_Features_Suppliment_Aug72.pdf and so did the first rel4ease of MVS, OS/VS2, release 2 http://bitsavers.trailing-edge.com/pdf/ibm/370/OS_VS2/Release_2_1973/GC28-0661-1_Introduction_to_OS_VS2_Release_2_Mar73.pdf -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
