Issue/Introduction

Given a CLIST (which is intended to run under TSO batch TMP like IKJEFT01) that issues ISPSTART or equivalent command to start ISPF
in the TSO/BATCH address space, could it be run in foreground by BC1PTMP0 processor utility?

Resolution

That is not possible because, when the CLIST is executed in a foreground processor, ISPF is already active in the address space and any
subsequent invocation of commands like ISPSTART will fail with a message like:

 

Command rejected - 'ISPSTART' command not supported under ISPF.

ISPD226  Invalid command - Commands such as LOGON, LOGOFF, SPF, ISPF, etc. are not permitted.
