Back when there was such a thing as WSA, I ran TSO/ISPF in batch to give myself separate sessions and used a different profile PDS for each.
The advantage of SPLIT/SPLITV over multiple sessions is that the splits share data with each other. What I'd really like is a "son of WSA" using SCTP to communicate with multiple windows or tabs. Maybe also stealing some ideas from CMS and XEDIT while they're at it. -- Shmuel (Seymour J.)

LMPUT requires SYSDSN ENQ EXC, failing to trust PDSE serialization and precluding some use of LM services in multiple jobs. OTOH, within a job LMPUT's design precludes using SPFEDIT ENQ serialization, with risk of data corruption. Has vertical split any advantage over multiple emulator instances (in the UNIX tradition) or a single emulator instance (in the Mac/Windows tradition)? If ISPF were to support multiple windows in a single session (not in any future I foresee) the benefit might be variable pool sharing. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
