Use SESSCMD in a CLIST or REXX EXEC

When you use the SESSCMD command in a CLIST or a REXX EXEC, you can capture the response to the issued command in CLIST or REXX variables. A CLIST or REXX EXEC can then analyze the response and take the appropriate action. SESSCMD creates the output CLIST or REXX variables shown in the following table:
