To change your printer so that all subsequent files are automatically released to the real printer, enter:
spool printer nohold
If your virtual reader has the default status NOHOLD, input spool
files are deleted from the have been read.. To prevent this, enter: spool reader hold Reader files now held in the system until you issue:
spool nohold
and rereaj the files.
enter:
If you want to delete the files immediately, purqe reader all
Aqain, vou have the option of using the CHANGE command to control the HOLD of -specific reader files via the spoolid number.
The :ONT/NOCONT status of a spooling device controls the
concatenation of files. Since this is a characteristic of a spooling
device, it can be changed only by the SPOOL command. When CONT is in
effect, the spooling device ignores input end-of-file indicators and
output requests. For output devices, the effect is to concatenate multiple output
files one logical spool file.
For input devices the effect is to read files and ignore end-of-file
indicators until all files spooled to the virtual reader have been read. that time, the end-of-file indicator that is reflected to the virtual
machine depends on the EOFINOEOF operand setting of the SPOOL READER
command. EOF results in a unit exception that corresponds to pressing
the end-of-file button on a real card reader. results in a unit
check/intervention required status. VIRTUAL CONSOLE SPOOLING While is usually associated with unit record equipment, VM/370 also spools both input and output data that is displayed on your virtual
console. To start console spooling, enter the command:
spool/console start
If you wish to spool vour console data and not have it displayed on the
terminal, vou can enter:
spool console start noterm however, the (or default not effective until console spooling has been started. does not prevent the printing of: • commands entered from CP mode. i£ Also, the NOTERM • Commands entered on a display terminal in CMS EDIT mode. Section 3. CP Command Usage 19

When you to stop console spooling, enter the command:
spool console stop
This stOP3 any further spooling of console data but does not close the
console soool files. For that, you must enter the command:
close console
The converse is also true--closing the console spool file does not
automatically stop console spoolinq. REORDERIN3 AND PURGING SPOOL FILES If you want to change the sequence of your closed spool files, issue the ORDER to place your files in a specific order by device type.
Files can be reseguenced by spoolid or class, or both when using the ORDER command. For example: order printer 2468 1357 class c
resequences vour closed printer spool files as follows:
file 2468 file 1357
all =lass C files (in their oriqinal sequence)
other files in original sequence
To remove any of your closed spool files from the system use the PURGE =ommanl. Files can be specified individually by spoolid or by
class, or both. For example: purge 1234 class b
removes file 1234 and all class B files from the system. purge punch all
removes all punch files. purqe all
removes all files from all devices. The CHANGE, ORDER, and PURGE commands can be used only on closed
spool files that belong to you and have not yet been selected for DEDICATED DEVICES
If a devi=e's use is restricted to a single virtual ma=hine, that device
is a dedicated device. Some devices, such as disks and unit record in dedicated mode at one time and in shared or
nondedicated mode at other times. Devices such as magnetic tape drives
can only be used as dedicated devices. 20 CP Command Reference for General Users
