Hi All,
I was wondering whether there was a way in IDL to tell if two
save/restore files contain identical data, something like the
'diff' command in UNIX except useable within IDL. Two identical
s/r files are said to differ if I use the UNIX command, presumably
because they contain information about the time they were
created etc. Basically, I've written some code that performs
various IDL commands and I just wanted to check that the output
was the same as if I had typed it in interactively.
Any ideas?
Thanks in advance,
David

If the number of variables you're saving is manageable, you might
try just writing the variables to a file using OPENW and WRITEU.
Just be sure the data-types are the same, and you should be able
to compare the files to see if they're different.
