I tried it *now*! I didn't know about graphical way. It's nice, but I
am happy with my command-line version, as I can just save the whole
thing in a variable. I always journal my sessions, so
print,outputvariable is always available to see later in that
particular journal file. Thanks for pointing this way to me. It is
cooler than mine :) (Of course, my version of IDL is old. 6.0. So just
wondering if higher versions include 'color-coded' display as well!)
