This UDF is nice for Hex to Decimal conversions when one does not wish the additional baggage of the WILX extender.

#DefineFunction Hex2Dec(hex)
   str="0123456789ABCDEF"
   hex=StrTrim(StrUpper(hex))
   hexlen=StrLen(hex)
   dec=0
   for x=1 to hexlen
       dec=(dec*16) + StrIndex(str,strsub(hex,x,1),0,@fwdscan) -1
   next
   return(dec)
#EndFunction


;Example Usage
a="07D0"
b=Hex2Dec(a)
Message(a,b)

Here is a sample that uses the Huge Math Extender for very large number conversions

#DefineFunction Hex2Dec(hex)
   AddExtender("wwhug34i.dll") ; Huge Math Extender
   str="0123456789ABCDEF"
   hex=StrTrim(StrUpper(hex))
   hexlen=StrLen(hex)
   dec=0
   for x=1 to hexlen
	     by16 = huge_Multiply(dec,16)
	     ptr = StrIndex(str,strsub(hex,x,1),0,@fwdscan)-1
	     dec = huge_Add( by16, ptr)
   next
   return(dec)
#EndFunction

;Example Usage
a="FFFFFD81"
b=Hex2Dec(a)
Message(a,b)
Exit
