Oops - forgot about that, and assumed "easy" language did what was
actually written :-).

Sounds like a bit of a nightmare. The 'length' input to StdErr is
variable; if pulled out, it would not calculate the right value.

Never thought to check StdErr, but in the Omega routine there is not a
check for 0 before dividing. Turns out the 'barf' value for length is 2,
not 0, because of the way they do the calc. I did a quick-and-dirty
rewrite of the Omega routine to check for 0, and it does, indeed, run OK.
It IS called, even though it is 'not called' :-).
Turns out the minimum value this variable can take just happens to be 2<g>.

Thanks much for the suggestion. I don't actually use that chunk of code
here (a leftover from another routine) and actually removed it. Also
improved the calc speed, too :-).
Your analysis of the problem was exactly correct.
Many thanks,
