This teletext editor will allow you to
write files for use with MO7DIS.
When the program is run there are two
lines of text at the top of the screen,
and two lines of text at the bottom of
the screen. You cannot edit these lines
they are used to give prompts.
The top line tells you whether
the pixel editor is in effect
or not.
The second line gives a prompt
as to the action of the
function keys.
The bottom two lines are used
for input and a reminder of the
function keys.
This teletext editor was written with
MO7DIS in mind. It is intended to be
used to produce a text file which can
then be assembled into a mode 7 display
file.
The top line of the display informs you
whether you are in pixel editing mode
or text mode. Pressing COPY toggles
between pixel editing mode and text
mode.
If the pixel editor is on, pressing
QWASZ or X will toggle individual
pixels on and off. Remember to put a
graphic colour code on the screen
before attempting to edit pixels.

by function keys. They are indicated on
the second line of the display.
