Althoug I'm familiar with f.e. Pascal I always used FORTRAN 
(FORTRAN-IV; F77) for my programming. The main reason is that
in FORTRAN it is possible to use complex numbers, while it offers
an extensive set of intrinsic complex functions (CEXP,CSQRT,etc.),
which are essential in wave-analysis.

Although it is possible to define new types or records in Pascal,
one is always confronted with problems when trying to write complex
functions is Pascal since the output of a function can never be
two values, i.e. real and imaginary. Therefore one is forced to
use subroutines for even the most simple problems, making your
code unreadable, and time-consuming.

I was informed that originally in c-language it was not possible
to use complex numbers in the way it's done in FORTRAN as well. 
However, can someone tell me if it can be done in c++?? Or are there
any other languages able to deal with complex numbers. Not that 
I want to switch from FORTRAN to c, since many FEM-packages are
programmed in FORTRAN, but I'm preparing "statements" for my
thesis, and one is supposed to deal with programming and complex
numbers.

please answer on the net or my e-mail adress.
Sincerely, Peter.
