Chris,
The meta problem is that the error handling from the interpreter is
terrible. Now that I've modified the interpreter to let messages have
content other than fixed strings, I can fix this.
I would like the interpreter to output a message that looks like:
Bad character near line 79
X-0.010+#177 Y3.0+#177 ( Back to Starting Position )
^
(alternatively, use a leader before the marker -- and/or a different marker)
............|
Note that there are three lines to this error: the text, the bad line, and a
line containing the marker "^"
Doing this would raise some issues:
1 -- Some error messages would be more than a single line
2 -- Error messages might be more than 256 characters (the present max line
length)
The hardest part of implementing this is caused by the fact that the
interpreter converts everything to upper case (or is it lower; I forget) and
removes whitespace before it actually parses the line. So to do it right,
the original line would have to be saved and the pre processing undone for
the purpose of error handling.
Would Axis (my present favorite gui -- although I'm not using it yet on my
machine) be able to handle long, multiline error messages?

The file has several lines (I didn't look for all of them) that
attempt to do math, either addition or subtraction, without square
brackets. As Ken L points out, this is not allowed:
X0.510-#177 Y1.5+#177 ( Cut to other side of slot )
...
X0.510-#177 Y1.5+#177 ( Step back out of Corner )
...
X-0.010+#177 Y3.0+#177 ( Back to Starting Position )
