True for the unauthorized/authorized case Shmuel mentions, but under
TSO/E, the ISPF main task does attach multiple concurrent tasks, one per
logical screen...three logical screens, three concurrent tasks:
1 IEAVAR00
2 . IEESB605
3 . . IKJEFT01, JOBSTEP
4 . . . IKJEFT02
5 . . . . IKJEFT09
6 . . . . . ISPF
7 . . . . . . ISPTASK (ISPLLIB)
8 . . . . . . ISPTASK (ISPLLIB)
9 . . . . . . ISPTASK (ISPLLIB)
