ZCOM Tokens
ZCOM-TKN-PATH-SWITCH-CAUSE 
This token appears in ZCOM-EVT-PATH-SWITCH event messages to specify the 
cause of the reported path switch. Valid values and the causes they represent are:
ZCOM-TKN-REQID-CPU
This token carries the process CPU number of the requester. The SCP process adds 
this token to requests bound for converted subsystems.
ZCOM-TKN-REQID-PAID 
This token carries the process access ID (PAID) of the requester. The SCP process 
adds this token to requests bound for converted subsystems. The value of this token is 
useful for security validation. If the subsystem was not converted, SCP adds 
ZCOM-MAP-REQID instead.
