3203 80DEL 5 PRIITER SUPPORT Changed: Documentation V8/370 supports the 3203 80del 5 printer in the same manner as the 3203 80del 4 printer.
SHARED SEG8EIT 80DIFICATIONS I!!: Program and Documentation V8/370 now places the user in console
function mode if he modifies a protected
shared segaent; it returns the modified page to free storage. V8/370 continues
to give other users of the segment
access to a fresh copy of the .odified
page. This is discussed in the "CP" Introduction" section of this
publication.
The LOADSYS diagnose function is
changed. When LOADSYS is executed, CP
finds the system name table entry for
the naaed system. In AP mode, two sets
of page and swap tables are built, one
for each processor. This is done for
each shared segment in attached
processor sode unless the named segment was defined as unprotected. lew abend codes are also added.

The YM/370 Measurement Facility
(!onitor) has been enhanced to extend
its data collection and recording
capabilities. These enhancements
include: • The gathering of additional data
related to utilization of channels, davices, ~~uLa~e, alterna~e 1/0 paths, and AP/UP PROCESSING. • Selective programmers which seek

when the YM/370 Monitor is to close
the spool file. A new subroutine, DMKENTTI, is added.
It is a high-frequency I/O status sampler that tests for busy conditions
in all control units and devices by examining appropriate CP control blocks
and in all channels via TCB
instructions. A new subroutine, DMKENT62 samples the
data accumulated by DMKENTTI and writes
it in a new class 6 code 2 record, after
the standard class 6 (DASTAP) code 1
record has been collected in D!K!ONTI. This information is contained in the "CP Directories" section of this
publication. 4331 AID 4341 PROCESSOR SUPPORT lew: Documentation YM/370 provides support for the 4331 and 4341 processors and the 3278 Model 2A display station as a system console for
these processors. The character set on
the 3278 Model 21 is the same as on the
current 3270 display systems, plus six
additional graphic national usage
characters that are acceptable in input
and output data streams. New modules and their entry points have
been added to the "Label-To-Module" and "Module-To-Label" cross references in
this publication. SPECIAL MESSAGE FACILITY !~: Program and Documentation
A new CP co.mand, SMSG, is provided to
allow a terminal user to send a message to another user's virtual storage. The
receiving virtual machine must be
prepared to receive the message. This
is done by issuing a VeCF AUTHORIZE and
setting seSG ON prior to receiving a message. Information about Special Messages is
found in the "CP Introduction" and "CP Directories" sections of this
publication. IBM 3850 MASS STORAGE SYSTEM (eSS) SUPPORT !~: Program and Documentation Virtual machines operating CMS, OS/'S1, or OS/VS2 (MVS) can access mass storage volumes containing V!/370 minidisks or
entire mass storage volumes dedicated to
the virtual machine. These volumes will
appear to .the virtual machine as 3330 volumes and will be accessed using 3330 device support. CF controls unit
allocation, volume mounting, and volume demounting. Virtual machines running OS/VS1 or OS/VS2 (MYS) and that contain !SS support can also access mass storage volumes using dedicated device support.
Com.unication with the Mass Storage Control (MSC) component of MSS is
provided by service virtual machines operating either OS/VS1 or OS/VS2 (!VS). The 'M/370 control program initiates volume mounts and demounts via intersystem communication with an
application program (DMK!SS) running
under either OS/VS1 or OS/VS2 (e,S). For information about the logiC of the D!K!SS application program, see the .!AL37 0 servi.£! J2.gti.!!~ jrogI!.! ~gic A~yal, Order Number SY20-0882.
