Actually the error quoted, that IDL has "reached the end of file before the end of the
program" sounds more like a corrupted source code file with an unterminated (or
incorrectly terminated) control construct. I get that error sometimes when I quickly
fiddle with IF constructs when testing code.

It can be a bugger to find this stuff as IDL doesn't report a useful line number (it
reports the last END as where the error occurred.... which, strictly speaking, is correct
but not too helpful.)

But, without more info, the above is just a guess.

p.s. I use Liam's imagemap successfully all the time and wonder what is meant by "the most
common complaint idl has with this program..." What other complaints do you get, Alison?
