Folks,
Before I re-invent the wheel, I thought I would ask.
I wish to write an ASCII text file with two columns of
text. The first column should be 30 characters wide,
the second column should be 45 characters wide.
BUT, I wish the data in the columns to be *left*
justified, not right justified.
What trick to you use, or what formatting string will
give me this kind of output?
Cheers,
David

I haven't gotten rid of the darn thing, because it seems
to me there ought to be a use for it somewhere. Probably
where you are making lists of things in a widget, and you
want the list left justified...
Cheers,

If it makes you feel any better, I wrote my own left-justifier a
couple months back, being likewise unable to find that format
code anywhere in the documentation. Now to go rip it out and
replace it with a '-' ...
