Hello.
You should not consider doing this in C. It would be a lot more
work, and give you no benefit over doing it in Perl.
Your attachment did not reach the mailing list. Perhaps you
could post it online somewhere, and provide a link to it? Or try
sending it to the list again?
In general, you will probably want to:
Read each line into a string (via the -n command-line option, or
via the "diamond operator" <>)
Split each line into an array of values (via the -F command-line
option, or the split() operator)
Reformat each value, and output them (via printf).
So it looks like you have the right idea. Please try sending the
attachment again, and also please let us see what perl code you
have tried so far.
Yours,
Eric Roode
