Can you recommend a soap brand that doesn't taste too bad?

In fact, I only quoted from the IDL online help:

"In the vast majority of cases, floating-point underflow errors
are harmless and can be ignored."

I don't like statements like this either, but !EXCEPT=2 really
slows down my code too much ;-)

Cheers (with no exceptions),

Martin
