/* DEC *MultiplyAscii(pDst,pSrc1,pSrc2)
*
* ARGUMENT
* pDst is a poiter to the destination DEC structure
* pSrc1 is a pointer to source1 ASCII string
* pSrc2 is a pointer to source2 ASCII string
*
* DESCRIPTION
* Multiplies the value in pSrc1 (ASCII) to the value in pSrc2 (ASCII)
* and puts the result in pDst DEC structure
*
* SIDE EFFECTS
* On error, the dest structure is undetermined.
*
* RETURNS
* Returns a pointer to the dest structure on success,
* otherwise returns a GM_NULL(a C false). On error, the error
* is in wGMError, unless an error was already there.
*
* POSSIBLE ERROR CODES
*
* GM_NULLSTRING
* GM_NOMEMORY
* GM_CNVRE
* GM_CNVRW
* GM_NAN
* GM_OVERFLOW
* GM_UNDERFLOW
