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.

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 -- David Fanning, Ph.D. Fanning Software Consulting, Inc.
