Programming
Spaces and tabs are allowed anywhere on a line of code and do not change the meaning of the line,
except inside comments. For example, the line:
G00 x +0. 12 34y 7
is equivalent to:
G00 x+0.1234 y7
Blank lines are allowed in the input, but are ignored.
Input is not case sensive, except in comments, therefore any leer outside a comment may be in
uppercase or lowercase without changing the meaning of a line.
