IMAGE LIB loads the new or changed text files created by GENIMAGE into vir
tual storage. When all the files are loaded, DIAGNOSE Code X'74' is invoked to
save these files as a named system.
IMAGEMOD makes selective modifications to an existing3800 named system
without completely regenerating the named system. While IMAGELIB creates a
new named system each time it is invoked, IMAGEMOD allows users to add,
delete, replace, and list members of a3800 named system. IMAGEMOD uses
DIAGNOSE X'74' to load and save the named system.
See the VMI SP Planning Guide and Reference for more information on
IMAGELIB, GENIMAGE and IMAGEMOD.
Storing and Loading Control Tables
Recovering fromI/O Errors
As part of VM/SP support of the3800 printer, character arrangement tables, copy
modifications, graphic modifications, and FCBs are stored in a named system.
Prior to printing a spool file, the VM/SP operator specifies a named system on the
IMAGE parameter of the START command. The control tables specified for the
file (via theSPOOL and CHANGE commands) are loaded into the 3800 from that
named system and the file is printed.
TheNAME3800 macro instruction establishes the named system at system gener
ation. See the VMI SP Planning Guide and Reference for further information.
Because the actual printing of lines on the page is slower than the output of lines
from the processor, spool files are placed into a delayed purge queue to await print
ing by the3800. Only when the maximum number of files are in the queue will the
first one actually be purged. The size of the queue can be specified at system gen
eration time via the DPMSIZE parameter on the RDEVICE macro instruction.
DPMSIZE can have a maximum value of nine.
Because spool files are queued, the BACKSP AC command may be used for the3800 printer to restore pages that are lost when an 110 error occurs. In addition,
the operator may specify theEOF parameter, which indicates that backspacing
should begin at the end of the file and continue for the number of pages specified.
See the VMI SP Operator's Guide for more information on the BACKSP AC com
mand.
Displaying Printer Control Information
The QUERY command enables G-, B-, and D-privilege users to display the names
of the character arrangement table, copy modification, and FCB currently in effect
for a spool file or a virtual printer. In addition, the VM/SP operator can use the
QUERY command to determine the image library used and the forms loaded on a
real3800. See the VMISP Operator's Guide for details on the QUERY command.
Using the3800 Printer as a Virtual Spooling Device
VM/SP enables a user to create printer spool files on a virtual3800 printer defined
for his virtual machine. VM/SP provides full support for the copy modifications,
forms overlay, character modifications, and multiple copy features. In addition,
