/* DEC *AddUnsLongToDecimal(pDst,pSrc1,l)
*
* ARGUMENT
* *pDst is a pointer to the destination DEC structure.
* *pSrc1 is a ptr to the source1 DEC structure.
* l is the unsigned long to be added to pSrc1.
*
* DESCRIPTION
* Adds the value 'l' to pSrc1 and puts the result in dest DEC structure.
* The sum is calculated to the maximum possible accuracy.
*
* SIDE EFFECTS
* On overflow, the dest value is indeterminate.
*
* RETURNS
* Returns a pointer to the dest structure unless overflow,
* when it returns a GM_NULL. On error, the error
* is in wGMError, unless an error was already there.
*
* POSSIBLE ERROR CODES
*
* GM_NULLPOINTER
* GM_OVERFLOW
*
