TRACEOFF
Use the TRACEOFF command to deactivate tracing.
Enter TRACEOFF on the OPTION line of the selection panel.
TSO/E redisplays the particular panel with the command still on
the OPTION line and with the following message:
CLIST or REXX exec trace is turned off.
If you enter TRACEOFF when trace is not active, TSO/E displays
the following message with the alarm option:
CLIST or REXX exec trace is not active.
