What confused me is what was meant by "compled err".  Say what?   Huh?

Anyway, I addressed in another response just how trivial it would be to
define a complex number as a C "struct", and write a set of routines for
the necessary manipulations (arithmetic operators,
input/output/transformation from and to strings, etc).  In C++ one could
even overload the normal arithmetic operators for that.  Not an issue at

Indeed a definition and set of routines to do the computational part of
a "complex" data type exists in the book "Numerical Recipes in C".
Takes all of 3 pages.
