Right. You should have a line, usually the first one, that is a "format
specifier". This part is completely foreign to the RS-274D spec,
in G-code it looks like a comment.

%FSLAX2.4Y2.4

This would mean format spec, L for suppress leading digits, then
A for absolute positions, and then the X and Y axes are both set to
2.4, meaning 2 digits to the left, and 4 to the right of the implied
decimal point.

The normal spec of RS-274D allows this, but doesn't provide this
FS mechanism for carrying the format definition along IN the file.
