Yeah, yeah. IDL is confused. It thinks a function call
is a variable reference. I get that that. I even understand
how this works internally (more or less).

What I don't get is how THIS line causes the confusion:

bar = BYTSCL(bar, TOP=(ncolors-1) < (255-bottom)) + bottom

And this line doesn't:

bar = BYTSCL(bar, TOP=(ncolors-1 < (255-bottom))) + bottom

Any insights into that?

Cheers,

David
