OKIGRAPHICS
A Graphics designer for the Okidata Microline 93
(c) 1984 by Neil J. Rubenking
╔═════════════════════════════════════╦═════════════════════════════╗
║ I release this program into the ║ ║
║ public domain. If you create a ║ Neil J. Rubenking ║
║ particularly great design with ║ 300 Page Street ║
║ it, I would very much appreciate ║ San Francisco, CA 94102 ║
║ receivinging a copy (on disk) ║ ║

With OKIGRAPHICS you can design a graphics pattern on-screen, dot by dot,
and save it to a file or print it directly to the printer. You can also
retrieve such a file for further editing. You can TYPE a file created by this
program directly to your printer ("type (filename).OKI>prn"), so you may use
it to create a title page for a report, and then print the title page from a
batch file.
OKIGRAPHICS is still rather rough-hewn. It has no capacity for saving
parts of images for later use, or even for copying an image to another part
of its screen. It is pretty much a dot-by-dot affair. Also, because of the
way it manipulates its huge array of potential dots, it is amazingly slow.
(For programs of this size written in TURBO PASCAL, anything but an instant
response is amazingly slow!). Also, there is no I/O checking -- if you ask
to retrieve a file that does not exists, you will CRASH. All that aside, it
does the job.
OKIGRAPHICS COMMANDS
OKIGRAPHICS shows a 42 row by 80 column window of dots at any time.
This prints as a rectangle about 1/2" by 1 1/3". You can move this window
using <Ctrl> + left, right, PgUp, or PgDn. The maximum up-and-down dimension
of a "big picture" is 20 of these screens -- across, it's 8 screens. Thus,
if you have the patience, you can create an APA graphics design about 10"
square. <Ctrl>+ Home and End moves you to the top left or to the bottom
right of the "big picture".
The keypad arrows move in the direction you would expect, and the keypad
"corners" move you diagonally. If the Scroll Lock is on, moving around with
the keypad leaves a trail of dots set. (I always end up with one too many or
too few!)
F1: set a dot
F2: erase a dot
F3: print--either to printer or to file
F4: retrieve file
F7: re-initialize (blank the "big picture")
F9: blank the current screen
F10: QUIT

"Anagram.OKI" and "Dict.OKI" print out the words "ANAGRAM" and
"DICTIONARY" in letters about 1/2" high.
