August 2007 Technical Tip – TSO/ISPF: Using the START command for more than two screens
Most TSO/ISPF users are familiar with the use of the SPLIT (F2) and SWAP (F9) commands. But with the SPLIT command you are limited to two logical screens, and sometimes you want more than two. For example, a programmer may find it useful to have an edit session open for their source code, another edit session open for the compile JCL, another edit session open for the execution JCL, and finally an SDSF (or ISPF, Flasher or WSF2) session open to view compilation and execution results. But how do you get four logical screens at one time? This is accomplished by using the START command instead of the SPLIT command, and using SWAP NEXT or SWAP LIST command instead of the SWAP (alone) command. The START command allows you to pen up to eight sessions at one time. This guided tour will show how this is done.
If you like the idea of many sessions, you might want to use the KEYS command to reprogram the F2 function key from SPLIT to START and the F9 function key from SWAP to SWAP NEXT (or SWAP LIST, your preference.)
