Use LOADBUF to load the following:
v The universal character set (UCS) buffer with a specified print chain/train image
for the IBM 3203 model 5 printer, 3262 printer, or a device that emulates a 3211
printer.
v The forms control buffer (FCB) with a specified image for the IBM 3203 model 5,
3262, 4245, 4248 printer, or a device that emulates a 3211 printer.
Notes:
1. You cannot load a UCS for a 4245 or 4248 printer.
2. The INDEX option is valid only for devices that emulate the 3211 printer.
3. To load the forms control buffer (FCB) with a specified image for a virtual
printer, use the LOADVFCB command.
4. The number of lines to be printed on the separator page is determined by the
FCB loaded on the printer. The default separator page contains 58 lines of data.
If the page length defined by the FCB is less than the default separator page
length, the separator page data must be customized in order to fit on a single
page. This may be done using CP Exit points that are provided in separator
page processing. See the z/VM: CP Exit Customization for details.
rdev
indicates the real device number of the printer whose buffer is to be loaded.
NOFOLD
Fold
If FOLD is specified, all characters will be printed in uppercase.
If NOFOLD is specified, the characters will not be not folded into uppercase.
If neither FOLD nor NOFOLD is specified with the UCS option, then NOFOLD is
the default. FOLD is used when a file specifies lowercase, but no lowercase
UCS is available.
If neither FOLD nor NOFOLD is specified with the FCB option, then the
FOLD/NOFOLD selection on the printer will not be changed.
LOADBUF
Note: If you specify the FOLD option, the control unit ignores bit positions 0
and 1 of the EBCDIC code when comparing the character codes from
