This routine lets you prevent selected commands from executing on the local system because of a cross-system command issued from an external system. CA MIC uses the GCMRCVXT exit routine whenever a cross-system command is received on the local system. You cannot use the GCMRCVXT exit routine to change the text of commands or the information associated with a command. You can use the MIMCMDXT exit routine to change the text of commands. For more information, see the CA MIM Resource Sharing for z/VM Programming Guide.
A sample GCMRCVXT exit is provided on the distribution tape. The sample exit prevents users on external systems from executing a CP command on the local system, and illustrates how selective control can be exercised over cross-system commands.
