Figure 18. Sample IPL of VS1 under VM/370 (Part 2 of 2) When using CMS, initial operator commands can be incorporated into a CMS EXEC procedure as part of the job stream. For example: To create
the following EXEC procedure called SETUPVS, issue these commands:
CP LINK VSSYS 250 250 RR OSPASS CP DEFINE 009 AS 01F CP IPL 250 After starting the appropriate as/vs readers, the virtual machine is ready to receive input from card readers, DASD, or tape drives. COMMUNICATING WITH CP
During as/vs virtual machine operation, a user can issue CP commands to
(1) communicate with the VM/370 system operator or other virtual
machine users, and (2) query and alter the status of the configuration
and spool files. In general, a user can enter any of the CP commands
normally permitted under his userid's privilege class.
Entering CP commands while an OS/VS virtual machine is running
depends on the terminal mode (as defined by the CP TERMINAL command or
its default value). When not running as the VM/370 system operator, the
default terminal mode is VM. In this mode, pressing the attention key
(er its equivalent) once passes an interruption pending condition to the
as/vs virtual .achine. pressing the attention key twice places the
virtual machine in the CP command environment from which CP commands
can be entered. For a complete description about how to use the
attention key, refer to £R !2£ Section 4. as/vs in a Virtual Machine 131

In most cases during virtual machine operation, a user can use the tcp
function te enter CP commands directly from the virtual machine. If the
virtual machine has issued a read to the terminal, enter a CP command
with the #CP function. For example: When no longer using virtual tape
drive 397 mapped to real tape drive 492, issue:
#cp detach 397 tcp msg cp i am done with real drive 492 VM/370 immediately processes these command lines, and the virtual
machine read remains outstanding.
Note: A user may not always be able to enter CP commands with the tcp function. The read issued by as/vs at the terminal must be for at least
as many bytes as entered in the #CP command line; any additional
informatien is truncated. If the read is for at least three bytes,
enter the iCP command. This command places the user in CP command mode
from which CP commands can be entered directly. To return to the
virtual machine environment, enter the BEGIN command.
Using OS/VS In Batch Mode Under VM/370 When many users submit jobs to a single as/vs virtual machine, someone
is generally needed to tend the machine as an operator. The virtual
machine oFerator must make those decisions required of an operator on a
real machine; that is, deciding what work is going to be done and what
is the most efficient way of doing it.
In batch mcde, one user runs as the as/vs machine (userid OSVS) and
other users (like CMSI01) may submit jobs either through the virtual
card reader, through the system card reader, or through JES remote
stations. If the card reader is not dedicated to the CS/VS virtual machine, place an 10 card at the beginning of each job stream, such as: USERID asvs A
In this card: the USERIO (or 10) indicates the valid beginning of an ID
card, asvs is the name of the VM/370 user to receive the card input in
his virtual reader, and A is the VM/370 reader class. If the VM/370 system operator has dedicated a card reader to the OS/VS virtual machine, then the 10 card must be omitted at the beginning
of the deck.
A user can send jebs to the as/vs machine from other virtual machines
by spooling his punch to the as/vs userid, such as: tcp speol punch to osvs
Entering this statement causes subsequent punched output to appear in
the virtual card reader for userid asvs.
