Suppressing Passwords Entered on the Command-Line
CP optionally rejects LOGON or LINK commands that have the password entered
on the same line as the command. Rejecting these commands prevents passwords
from being displayed or from being printed without masking --masking a password
means overprinting the password so it cannot be read.
This capability is also available to virtual machines that issue LINK commands via DIAGNOSE Code X'08'. For a description of DIAGNOSE Code X'08', see the
section "DIAGNOSE Instruction in a Virtual Machine."
To request password suppression, specify it as an option on the SYSJRL macro
instruction in module DMKSYS during system generation of VM/SP. Once requested, password suppression is always on; an operator cannot turn it off. Refer
to the VM / SP Planning Guide and Reference for information on how to use and
code SYSJRL in DMKSYS.
