/* int	ReturnMathErrAndClear();
 *
 * ARGUMENT
 *
 *
 * DESCRIPTION
 *	Sets wGMError to GM_SUCCESS, and returns it's previous value.
 *
 * SIDE	EFFECTS
 *	Does NOT clear the variable wGMErrFunNum (function number
 *  causing error). This is so that ReturnErrFuncNumAndClear() can
 *  get	and clear that one separately. If you want to write your own
 *  functions, or do your own checking,	remember that wGMErrFunNum
 *  may	contain	an error function number, but wGMError could have
 *  been cleared by some previous call to here.	 Function ClearMathError()
 *  unconditionally clears both	and can	be found in "gm.h". BE SURE YOU	ARE
 *  A SOURCE CODE USER AND KNOW	WHAT YOU ARE DOING WITH	THESE
 *  VARIABLES, AND HOW THEY ARE	AFFECTED BY THE	INTERNAL ROUTINES,
 *  BEFORE YOU WRITE YOUR OWN ERROR HANDLER!
 *
 * RETURNS
 *	Returns	value of wGMError (before settting it to GM_SUCCESS).
 *
 * POSSIBLE ERROR CODES
 *
 *	None.
