Is it possible to invoke BMC AMI Ops SYSPROG Services as a TSO command? 

BMC AMI Ops SYSPROG Services operates as an authorized program within the Product Address Space (PAS), as a TSO command within a TSO address space, as a batch job, as a Started Task, or from BMC AMI Ops Automation.

You can invoke the product as a TSO command, in which case it operates in line mode.

Note: Before you can execute the product as a TSO command, you must add SYSPROG to the AUTHCMD and AUTHPGM lists in the IBM PARMLIB member IKJTSOxx. For more information, see the IBM publication MVS Initialization and Tuning Reference.

In addition, if SYSPROG Services is running with the BMC AMI Ops Monitor for z/OS product, you can use the SYSPROG AUTHTSO service to update the in-storage copies of those lists to enable the use of SYSPROG Services as a TSO command without having to perform a system IPL.
