LOADVFCB
Messages
2. If you are running a program in your virtual machine that requires printer
overflow sensing information and you are printing on a real 1403, you need to
take special steps to retrieve the sensing information. First, ensure that the CP
directory entry for your virtual machine indicates that the printer is a 3203, 3211,
3262, 4245, or 4248, even though the program and the guest operating system
in which the program runs define the printer as a 1403. Then use the
LOADVFCB command to specify a virtual FCB image that matches the 1403.
CP uses this virtual FCB image as a basis for retrieving sensing information.
3. If the virtual machine operating system issues a LOAD FCB channel command
word to the virtual spooled printer, the LOAD FCB CCW image replaces the
virtual FCB image provided on the LOADVFCB command line. Note that the
CMS PRINT command issues a LOAD FCB CCW and thereby replaces the
virtual FCB image.
4. The LOADVFCB command allows specification of the extended FCB image for
a virtual 4248 printer. If an attempt is made to send the extended FCB image to
a printer that does not support the extended FCB format, an error message
results.
5. If the default FCB image has been modified, the virtual FCB image from the
spooled printer is stored in any file created on that printer. When the file is
printed on a real printer, the FCB is loaded into the real printer according to the
FILEFCB or DEFFCB option specified on the START command. The file then
prints properly on the real printer.
