As an additional aid when entering the commands and responses
necessary toIPL DOS/VS from the card reader, use the ceNT option of the SPOOL command. This option allows a user to spool the IPL commands and
jcb stream as a single spool file. For example:CP SPOOL PUNCH NOCONT CP CLOSE PUNCH PURGE CP CLOSE C CP PURGE READER ALL PUNCH SUPER JCL (NOH CP SPOOL 0 CONT PUNCH START JCL (NOH PUNCH DOSTEST JCL (NOH CP SPOOL 0 NOCONT CP IPL 250 When spooling the punch with the CONT operand, VM/370 spools the STABT JCL and DOSTEST JCL files as a single spool file. When the IPL commands
are read,DOS/VS continues reading from the card reader. A user does
not have to signal (with a null line) whenDOS/VS is to begin reading
the job stream.
Continuous spooling bas an additional advantage in theIPL procedure. When issuing the IPL command, the virtual punch is closed. However, in
the previous example where the punch was spooledNOCONT, but not closed,
theIPL closes the punch. As the file is spooled to the reader, this
action causes a reader interruption, which is the first interruption
that a user has to enter (the one that causesDOS/VS to read the
supervisor name).
Thus, when executing thisEXEC format, a user is required (after the IPL command is executed) to enter only one interruption and one REA£Y cOlmand to execute the entire job. The console sheet might look like
this:
dosjob
! !
displaypsw PSi = 030EOOOO 000128000 ready OOc begin
After issuing this BEGIN command, the remainder of the job is executed
without user intervention until the card reader is empty.
TheeMS EXEC facility is described in detail in the Using More Than One Virtual Machine
In aDOS/VS virtual machine, if a user is running a job that may take a
1cng time to execute, he may want to free his terminal for other work.
In these situations, use theDISCONN command to disconnect the DeS/VS virtual machine and log onto some other userid.
This tOFic shows a sample procedure (using the useridsCMSPREP1 and DOSTEST1), followed by a list of some additional things that must be
considered when disconnecting a terminal.While it is not necessary to use CMS to prepare or transmit the
jobsto the DOS/VS virtual machine, users may find it convenient. 100 IBM VM/310 operating Systems in a Virtual Machine
