I've tried distributing files that I @filename
into the code, but this always causes me grief
when people try to run the code because it requires
that the directory where the @ files are located
be on the PATH (or in the local directory).

For some reason, people with UNIX machines have
a *great* many problems getting their paths set
up properly, in my experience. More often than not,
my files are in 5 different directories on their
machines, and I can easily spend an entire day
getting things on their path sorted out. :-(

I think it was two. But I try not to let the facts
get in the way of making a point, whenever possible. :-)

(For some reason, I was thinking of TV and TVIMAGE
when I wrote that response. It's true that TVIMAGE
uses ONLY built-in IDL commands.)

Cheers,

David
