It might be worth opening the resulting 'text file' in a hex editor
(debug will do in a pinch) and verifying that it contains exactly what
you think. MS Excell likes to put tabs between columns instead of
spaces and that might confuse the control. Also try typing in
identcial code by hand, using a single space between each word (ie
G01_X111_Y222 with spaces instead of underscores). The Bridgeport
Ex-Trak mills, for example, are really, really picky about formatting
characters which are not easily visible.in most ways a user would
view a text file.
