were not available or couldn't be realized through other means. Like I'd
said, using Fortran-77, I was doing such things for the US Navy in early
'80s. Most of the intrinsic features can be 'in-lined' whereas when you
are calling libraries of similar functions in 'C', you have call overhead
to contend with. It's impact is small unless you're exercising that code
often. How do you contend with "COMPLEX" numbers in 'C'? Sqrt(-1)*REAL
is a real number in many scientific computations.

perhaps, at the upcoming MARCH "Saturnalia."
My dealings are in the VMS realm but I know of a few companies still using
big blue iron that also develope their apps using COBOL. Banks, anywhere
there are classic accounting needs (AR/AP/O* type stuff), insurance co.'s,
and even a large US trucking co. I'm no COBOL programmer, thank goodness,
and I don't have much of a head for financials, but I believe one of the
COBOL strengths is its intrinsic packed or zoned decimal math.
C'mon, it was a little over a decade ago that the world was going to come
to an end due to COBOL whackers putting 3 digit years into production. ;)
