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

The IBM 3800 printinq Subsystem is a high-speed, nonimpact printer that
combines electrophotographic and laser technology. The 3800 printer can
achieve speeds of up to 20,040 lines/minute, while several unique
features give the user the ability to control the characteristics of
printed output.
The features of the 3800 printer include: • Forms control buffer -controls the amount of vertical space between
printed lines. The user can specify vertical spacing of 6, 8, or 12
lines/inch. • Multiple copy printing -allows the user to request multiple copies
without the use of carbon paper. The 3800 uses its hiqh speed to
repeat-print the specified number of oriqinals. • Copy modification -allows the user to print or suppress predefined
information on specified copies of a page. For example, a different
name and address can be printed on each copy of a page. • Forms overlay -allows
printed (flashed) from
inside the form.
the user to specify a forA or grid to be
a negative while output is being printed • Character arranqement tables -allow the user to specify
predefined character set will be used to print a data set.
character set contains up to 64 printable characters.

Each • Character modification -allows character sets to be modified or
extended to meet the user's needs.

real spoolinq device.
Using the 3800 Printer as a Dedicated Device VM/370 allows a virtual machine that is configured to support a real 3800 to attach the 3800 for that machine's exclusive use. When used as
a dedicated device, VM/370 supports all of the facilities of the 3800. 226 System Guide
