Password-On-The-Command-Line Suppression
Option YK/370 supports the password-on-the-command-line suppression system generation option through which an installation may now prevent
disclosure of virtual machine and minidisk passwords to unauthorized
personnel. This is accomplished by disallowing passwords entered on the same line as LOGON/AUTOLOG and LINK commands. When this option is
selected, passwords must be entered so that they are not displayed (as
is the case with the 3270 display family) or so that they are typed upon
a .ask (as is the case with the 2141 terminal) • If this option is
chosen, installation users are not able to include passwords on the same line as their LOGON/AUTOLOG and LINK commands. A virtual machine may also request CP to perform this same service
for LINK and AUTOLOG commands passed to CP from a virtual machine via
the DIAGNOSE X'8' instruction by turning on the high order bit in By (the length register) e CMS has also been modified to request
suppression of passwords for LINK and AUTOLOG co •• ands entered at the
terminal. Password suppression is not required by CftS for LINK or AUTOLOG commands entered from a module or EXEC. The password-on-the-command-line suppression option is system generation time by the new SYSJBL macro instruction.

the system Messages generated when the password is entered on the same line as a LOGON or LINK command are sent to the issuer of that command. YKBLOK COpy has been modified to reflect support of the
password-on-the-command- line suppression option. A new control tlock, JPSCBLOK, is used to control this option. SBL AND PROGRAM LOGIC PUBLICATIONS The following publications contain information

Remote Spooling Communications Subsystem (RSCS) Networking Program Product
The Remote Spooling Communications Subsystem Networking program product (Program Number 5748-XP1) is the successor to the current RSCS component
of VM/370 and the VM/370 Networking (VNET) programming PRPO P09007 (Program Number 5799-ATAj. The ases Networking prcgram product provides
Remote Job Entry into a VM/370 system and allows a VM/370 system to
participate in a network of computer systems that use the Network Job
Interface/Network Job Entry (NJI/NJE) protocol.
Phased migration to the RSCS Networking program product is possible
because RSCS Networking is a superset of either the RSCS component of V8/370 or the VNET PRPQ. RSCS Networking is compatible with both of
these facilities, except that the RSCS operator will see minor parameter
incompatibilities in the TRACE, and CMD commands. The RSCS Networking program product can coexist on same processor with the RSCS component of VM/370 Release 6 provided that each has its own
separate DASD space.
