Hmmm! These solutions are all very elegant, aren't they? Gives me a
headache, though! There's something in my IDL manual about avoiding IF
statements.......

For the less accomplished among us, and I'm included, if the parameter
you're trying to pass is an unsigned integer, add 1 to it before you pass it
to the subroutine and then subtract 1 when you get in. Easy. And you
didn't have to spend ages with the manual either (actually, there's 8
manuals with my IDL and it's a nightmare to find things - it was better when
there were only 2!) :)
