uee BUFFER IMAGES The uee buffer contains up to 240 characters and supports the 1403 printer. To add a new uee buffer image, first code the uee macro. This
creates a 12-byte header for the buffer load that is used by the ep
module DMKeSO. The format of the uee macro is:
uccname
uee uccname
is a 1-to 4-character name that is assigned to the buffer
load.
Next, supply the exact print image. The print image is supplied by
coding Des in hexadecimal or character format. The print image may consist of several Des, the total length of the print image cannot
exceed 240 characters.
The ueeeew macro must immediately follow the print image. This macro
creates a eew string to print the buffer lead image when VER is
specified by the operator on the LOADBUF command. The format of the
ueeeew macro is:
uccname
ueeeew uccname[,(print1,print2, ••• ,print12) ]
is a 1-to 4-character name that is assigned to the buffer
load by the uee macro.
[ (printl, ••• ,print12) ]
is the line length (or number of characters to be printed by
the corresponding eei) for the verify operation. Each count
specified must be between 1 and 132 (the length of the print
line on a 3203 printer) and the default line length is 48
characters. Up to 12 print fields may be specified. However,
the total number of characters to be printed may not exceed 240. Finally, insert the macros just coded, uec and Ueeeei. into the DMKuec module. This module must be reloaded. DMKuee is a pageable
module (with no executable code) that is called by DMKCSO. DMKuec must
be on a page boundary and cannot exceed a full page in size. 1: You do not have to specify the line length for verification
of the buffer load. Insert the following code in DMKUCC: UCC DC UCCCCW EX01 5CL'1234567890A ••• Z1234567890*/' EX01 224 IBM VM/370 System Programmer's Guide

Page of GC20-i807-7 As Updated April 1, 1981 by TNL GN25-0829 The buffer imaqe is 5 representations of a 48-character string
containing: • The alphabetic characters • The numeric diqits, twice • The special characters: * and /
since the line length for the print verification is not specified on the
uccccw macro, it defaults to 48 characters per line for 5 lines. Insert the following code in DMKUCC: UCC NUM1 DC 24CL'1234567890' UCCCCW NUM1,(60,60,60,60) The NUM1 print buffer consists of twenty-four 10-character entries.
If, after DMKUCC is reloaded, the command LOADBUF OOE UCS NUM1 VER is specified, 4 lines of 60 characters (the la-character string repeated
6 times) are printed to verify the buffer load). Part 2. Control Program (CP) 225
