Combinations of suboptions for the EQAOPTS SVCSCREEN command

The following table shows examples of combinations of suboptions for the EQAOPTS SVCSCREEN command:

Table 1. Combination of SVSCREEN options and their effects
SVCSCREEN options Type of z/OS® Debugger session Action
OFF,CONFLICT=NOOVERRIDE (default) z/OS Debugger started by using EQANMDBG Same as for ON,CONFLICT=NOOVERRIDE.
z/OS Debugger started by any other method
  • z/OS Debugger does not enable its SVC screening.
  • You cannot debug programs that do not run in Language Environment® which were started by programs that do run in Language Environment.
  • z/OS Debugger does not detect the MVS services LINK, LOAD and DELETE.
  • The CONFLICT setting is ignored when the OFF setting is specified.
OFF,CONFLICT=OVERRIDE z/OS Debugger started by using EQANMDBG Same as for ON,CONFLICT=OVERRIDE.
z/OS Debugger started by any other method Same as for OFF,CONFLICT=NOOVERRIDE.

The CONFLICT setting is ignored when the OFF setting is specified.

ON,CONFLICT=NOOVERRIDE z/OS Debugger started by using EQANMDBG If SVC screening is active, z/OS Debugger terminates. If SVC screening is not active, z/OS Debugger enables its SVC screening, runs the debugging session, and disables its SVC screening after the debugging session ends.
z/OS Debugger started by any other method If SVC screening is active, z/OS Debugger does not enable its SVC screening. You cannot debug programs that do not run in Language Environment which were started by programs that do run in Language Environment. z/OS Debugger does not detect the MVS services LINK, LOAD and DELETE.

If SVC screening is not active, z/OS Debugger enables its SVC screening, runs the debugging session, and disables its SVC screening after the debugging session ends.

ON,CONFLICT=OVERRIDE z/OS Debugger started by using EQANMDBG If any SVC screening is active and the NOMERGE option is in effect, z/OS Debugger overrides the existing SVC screening. This is also the default behavior. z/OS Debugger enables its SVC screening, runs the debugging session, and disables its SVC screening after the debugging session ends. If any SVC screening was active, z/OS Debugger restores the previous SVC screening. If you specify the MERGE option, see the following information about MERGE.
