Hello all, I'm having a problem with printing multiple columns in
IDL. The data I want to print to text is 300 columns, with 141 rows.
Right now it's printing them all out stacked on top of each other in
one column.

Well, I don't know. I suspected extra spaces that you
weren't accounting for, so the width+2 thing doesn't
surprise me as much as it does you. I think the extra
space is confirmed by the fact that the format statement
works with the original width. That is, your assumption
that the default format is the same as exactly 16*num
spaces is probably incorrect, no matter what it looks like. :-)
Cheers,
David
