CHARACTER DEFINER (16K ZX-81)
by Mazen Kisawi, North Ahmadi, Kuwait
from Your Computer, April 1984, page 191

This program enables ZX-81 users to define their own characters, using a ZX
Printer. Before loading the program type POKE 16389,124 and NEW.

In the top left-hand corner of the screen line 1 will be printed, and the
program then waits for an input. The character will be defined on an
eight-by-eight grid.

Whenever you want a dot on the first line, enter a full stop. Whenever you want
a blank, input a space. This continues for eight lines, working horizontally.

After the character has been defined you can either move to another character
or type in PLOT. After that there will be a short pause before the character is
printed on the printer. To save any character use the string-saving method. A
character is defined between B$(1) and B$(8).

[Enter EXIT to quit defining further characters, which causes the program to
stop with error report code E. If RAMTOP is not lowered before loading the
program, error report code then M will be displayed when the program is run.
After PLOT as been entered and the characters defined printed on the printer,
the program ends with error report R.]
