 **	Parameters:
 **		Error	error number which is to be trapped
 **		Message	pointer to a string to be printed as an error message
 **	Globals:
 **		ErrorTrapStack		stack of error traps
 **		CurrentTrapDepth	number of traps on the stack
 **	Operation:
 **		This routine prints the specified error message to stderr.
 **		It then jumps to the current error trap.  If the error trap
 **		stack is empty, the calling program is terminated with a
 **		fatal error message.
 **	Return:
 **		None - this routine does not return.
 **	Exceptions:
 **		Empty error trap stack terminates the calling program.
