Thanks, what exactly are the advantages? These are sometimes long calculations
so the processor will be running for long. Also, is there an example on using
times(2) somewhere? A Google search on times(2) example C did not reveal much,
but the choice of keywords may not have been apt. (One problem with the name of
the language  called C is that is just a letter, as opposed to
fortran/C++/pascal et al, which is more distinctive.

Sorry and thanks for all the help!

Best wishes!
