Pete,

  If you can provide a snip of code that invokes a FPE, then I can 
send you code to trap it.

    TTFN,
      Mike

  I wrote some stuff Monday night but nothing I tried (asside from kill
itself) would generate a SIGFPE, I tried all the simple things like
  a = 1.4 / 0.0;
  b = 1e150 / 1e-150;
  c = 1e-150 / 1e150;
  d = 1e150 * 1e150;
  etc...

(note that the compiler will warn about all of the above, so
I actually stuck things into variables and went through a few 
steps to do the above... but no SIGFPE)
