Trivial problem, no doubt, but I've never been able to get my brane
around formatting options.
I have a list of files, with the extension .01, .02, .03 ... .12. The
preceding portion is indentical in all cases.
I'd like to be able to load these in a loop, but I first need to convert
the counter value into this format.
My current, and very ugly, technique is to have an array filled with
['01', '02', ... '12'], and then reference the appropriate entry. It
works, but I don't like it.
Any ideas?
Simon

Not sure what you folks are arguing about. IDL has had the I0 format
code for as long as I've known, and does exactly what you want!

Example:
IDL> print, 1, format='("<",I0,">")'
<1>
IDL> print, 10, format='("<",I0,">")'
<10>

Yes, but removal of leading blanks via a format code would be handy for use
with TICKFORMAT.
