ISPF multi-tasks under TSO/E - The TMP IKJEFT01 attaches IKJEFT09 which attaches ISPMAIN which attaches ISPTASK, and each logical screen under ISPF is a separate ISPTASK subtask of the ISPMAIN task. Additionally, when you invoke the TSOEXEC command under ISPF, a sister task to the IKJEFT09 task is attached while the originating ISPF task structure waits. If you want to write a multi-tasking ISPF application, you can. There are no restrictions.
