Displaying String on Free42 & DM42

[Werner]

Hi Bill,
nice & thanks already for the huge effort in creating the FONTS program.
As a suggestion, I'd have 5 control characters: the 4 arrows and an 'escape' character to indicate that the following character is to be drawn, not interpreted, eg a quote. That way, there's no need to 'remember' the previous character.
Also, (I'm rewriting DISPLAY for my own needs ;-), I use a matrix "CTRL" of control characters. To then determine whether the current char is a control character, I use
[FIND], which verifies all of them in a single command. RCLIJ GTO IND ST X or Y can be used to branch to the specific control character code. If it's not found, [FIND] will skip the next instruction (should've been called [FIND?] instead).

Thanks, Werner
