I used standard Unix C++ compiler with the <complex.h> header file. This allows me to use the complex abstract data type in the main program.
Okay, but when I use the same program, after changing the necessary library file names for use on the MSDEV Visual C++ environment, I get the "unknown decl - identifiers" error message for the the ADT type "complex". It is accepted under the Unix compiler, but not under the MSDEV compiler.
xyu --> my code is about a thousand lines. So I can attach an email to you if you give me your e-mail address.
