Real Inhibit Support
This support adds to CP the capability of handling a read inhibit from a
virtual machine when entering passwords and other security data. The
read inhibit facility provides the capability for entering data so that
it is not displayed or so that it is typed upon a mask. The CCi command
code OE in a virtual channel program is used to a request
for a read inhibit from a virtual machine to CP. The determination cf
terminal device type and the way in which to inhibit a read is now
handled by CP. A virtual machine may now prompt a user to input his
password during some transaction .processing without revealing the
password on the display screen or on a spooled printer output copy,
thereby enhancing SRL AND PROGRAM LOGIC PUBLICATIONS The following publications contain inforaation on the read inhibit
facility: GC20-1801 System Programmer's Guide SY20-0884 Data Areas and Control Block Logic Section 1. Summary of Changes to the va/370 System 1-27

Automatic Reinitialization Support
This support allows a CMS virtual machine to specify that control be given to a reinitialization program as an alternative to entering a
disabled wait state after an abend. This support enables the virtual
aachine to check in the CMS nucleus for a new field, AUSERRST, which is
the address of the restart routine. If a valid address is present,
control is passed to it. This routine could issue an abend dump and
then issue the CP IPL PARM command with the new AUTOCR option. This
would enable a CMS virtual machine to automatically execute its PROFILE EXEC after an IPL command is issued. SRL AND PROGRAM LOGIC PUBLICATIONS The following publications
