Get_Error_String_MCH
               
Description: Accepts the error returns from other Software Tools.
This routine returns a char string containing a corresponding
error message.

Input parameters:  errorcode   The error code returned from a function call
		   errorlen    
Output parameters: errorstring	A message string that contains a
                              	corresponding error message. In case of bad
                               	input this routine returns a string denoting
                               	that.

Return values:  0		Always

Use this routine as per the following example:
#define ERRORLEN 255
   char ErrorStr[ERRORLEN];
   Get_Error_String_MCH(errcode, ERRORLEN, ErrorStr);
   printf("error is: %s", ErrorStr);
