I have to get from level 1.7b to 1.7e. I have received the UPD files. However, there is no information that I can find on how to proceed with them. I've scanned FILELISTs and MEMO files, but nothing seems to address this topic. No INITIAL SHIPMENT file was sent, but it may not be necessary. The 1.6 LISTINST MEMO says to CARD LOAD files, but refers to the files as being named VERS...., and in any case the UPD files contain Listserv JCL prologs which prevent CARD processing. Older documentation makes mention of a S01-005 Maintenance Guide, but no mention of how to GET it, or what is stored-file name is. I'd appreciate getting pointed in the right direction. Thanks.
