88 IBM VM/370 Operating Systems in a Virtual Machine

The reader file contains a job stream for the DOS/VS virtual
machine a 2. The DOS/VS system residence is assumed to be defined at virtual
address 250 in userid DOSYS's directory entry and have a write
password of ALL.
3. After the 1PL command, the attention interruption causes message OI03A to be issued. After entering the supervisor name, a later continues the 1PL procedure.
4. The SET and DPD commands are required to IPt DOS/VS. 5. The background partition is active and waiting for commands. The LOG command is optional; the ASSGN and SET commands shown here
may be required for system recordinq. 6. A null line signals an interruption to the card reader, so that DOS/VS begins reading the job stream.
7. These are ROE (reliability data extractor) messages; a null line
entered in response indicates that the user is taking the default
values.
8. DOS/VS continues reading the job.
9. The card reader is empty; the spool file has been read. 10. A null line causes another interrupt to the card reader; if
another file is in the card reader g it is read. Otherwise,
message OP08A is issued.
Figure 16. IPL DOS/VS and Execute a Job in the Card Reader (Part 2 of 2) 1PL FROM THE CARD READER Place the centrol commands for performing the IPL procedure in the card
reader of the DOS/VS virtual machine before issuing the IPL command to
lead the system. Then, signal DOS/VS to read the control commands from
the card reader. This method can be more efficient than entering all of
the control commands manually, especially if there are many ADD and DEL commands that must be issued when initializing DOS/VS. The cards required to perform the 1PL procedure must be in two
separate card files: (1; a single card specifying the supervisor name, and (2) a card deck containing the IPL commands. A user may follow
these card files with additional files that contain jobs for execution
in the DOS/VS virtual machine.
To load DOS/VS into the virtual machine, enter the 1Ft command:
