Electronic Vertical
Format Unit
.
This program will allow you to
program the prowriter printer for
vertical forms control. The program
is pretty much self documented, with
an example shown before the program
begins.
.
You can use this to change forms
lengths, anywhere from 1 to 96 lines,
and specify the channels to be used
for printing. You should also know
that a reverse line feed on the
prowriter will allow the paper to be
feed reverse to the channel
designated.
.
To use, run the program and follow
the example, then answer the
questions that are presented. After
you have answered all, the format
will be written to the Prowriter, and
you will be asked if you want to save
the format control to disk. If you
answer "Y", you will be asked for a
file name to give to this format.
.
In order to use this saved command
file you will need to run a quick
Basic program that looks like the
following:
.
10 DIM A$(200)
20 OPEN #1,4,0,"D:filespec"
30 INPUT #1;A$
40 CLOSE #1
50 LPRINT A$
60 END
.
This program will read the saved
format into memory, and print it to
the Prowriter, thereby allowing you
the luxury of creating multiple
formats and not having to run the
EVFU program each time.
.
An interesting note, if you format
the last channel before the end of
the normal page (62), the printer
will skip to the top of page when it
encounters this end of page. You can
therefore just LIST "P: " your
programs, and not have them run over
the paper perforations.
.
Hope you enjoy using this quick
utility program.
.
