Hey mark!

 ml> they don't really mean a whole lot

You've obviously never used a f77 compiler before.  :::cold shiver down the

Yes.  See my above comment.  I notice that on your quote that a tab at the
start of a line has an extra space.  Is there a reason for that?  Seems a tad
odd but maybe not if at start of line as there might be a reason for adding
additional character(s) for that special case.  I've seen it happen before.

Life is good,
