Oh, oh. I think my problem is that I'm not anal enough. :-(
It was gently pointed out to me that, uh, the SIZE function
isn't really doing anything worthwhile here, so why put
it in?
My only excuse is that you know how these things go.
You're standing around glaring at that &#*@ down-the-line
backhand that went long *again*, and an idea suddenly
comes to you. By the time you get back to the office
the sudden clarity has turned to mush and you cast around
for inspiration. In the end, the final result contains
unmistakable marks of your own muddleheadedness.
But this is only version two of a three line program. I must
be a better programmer than I think. It usually takes me at
least five versions to get it right. :-)
;*********************************************************** *********
PRO UNDEFINE, varname
IF (N_Elements(varname) NE 0) THEN tempvar = Temporary(varname)
END
;*********************************************************** *********
Cheers,
