// Author: Edward Hutchins
// Status: Freeware
// Revisions:
// 06/06/90 modified HUGE to LARGE to preserve compatibility with math.h
//          also nested windows.h include to prevent modifications on the
//          actual source file - Ed.
// 10/01/90 added CONST and CONSTP,NP,LP,HP and a few comments - Ed.
// 08/28/91 added EXPORT and SEGMENT - Ed.
// 10/28/91 added DLLEXP - Ed.
// 11/02/91 posted on Compuserve - Ed.
