Is ordering defined on type enum? I have a book on Turbo-C (can't remember the
title but it's published by Howard Sams) which says that ordering on the
elements of an enum is undefined. For example, enum { JAN, FEB, MAR } months
would make the comparison (FEB > JAN) illegal! I don't believe this is reality
in Turbo-C, but, I'm currently 1700 miles from my PC and library.
