Description

XPLRESP

This response byte must be set by the exit before returning to JES2. Set the response byte as follows:

X042CANC: This bit setting turned on in the response byte indicates that the notify message is to be canceled. Otherwise, the notify message is to be issued. This bit will be turned off on entry if no errors exist before the installation exit gets control, but will be turned on entry if errors are found before the installation exit gets control. If the exit corrects the errors detected, this bit setting should be reset to be off.
X042SETR: This bit setting turned on in the response byte indicates that both a return code and a reason code were specified in the parameter list. If this bit setting is not on, neither reason code nor return code are present.
X042NOCH: This bit setting turned on in the response byte indicates that the node has been changed. If this bit setting is not turned on, there has been no change to the destination node.
X042RMCH: This bit setting turned on in the response byte indicates that the remote has been changed. If this bit setting is not turned on, there has been no change to the destination remote.
X042USCH: This bit setting turned on in the response byte indicates that the userid has been changed. If this bit setting is not turned on, there has been no change to the userid.
X042MSGC: This bit setting turned on in the response byte indicates that the message text and length have been changed. If this bit setting is not turned on, there has been no change to the message text and length.
X042MEMC: This bit setting turned on in the response byte indicates that the member number in X042MEMB was changed by the exit.
X042MAIN: This bit setting turned on in the response byte indicates that the notify request should be unconditionally queued to the JES2 main task for processing. This allows the message to be seen by $EXIT 10.
