classlib.h

UC Library Extensions UnderC comes with a pocket implementation of the standard C++ libraries, wh

// CLASSLIB.H
// This concentrates all the assumptions about the iostreams
// and string libraries being used.  Personally I prefer the classic
// iostreams in console mode, and a hand-rolled string;  the std
// versions are too expensive in compilation time and executable size.
// The alternative libraries are all kept in the same directory to
// prevent confusion about include paths.
