Here is my brut force way of handling this
Names Default To Here( 1 );
theArray = ["0" => "0000",
"1" => "0001",
"2" => "0010",
"3" => "0011",
"4" => "0100",
"5" => "0101",
"6" => "0110",
"7" => "0111",
"8" => "1000",
"9" => "1001",
"A" => "1010",
"B" => "1011",
"C" => "1100",
"D" => "1101",
"E" => "1110",
"F" => "1111"];
theHex = "F061F997862C3E70";
theBinary="";
for(i=1,i<=length(theHex),i++,
theBinary = theBinary || (theArray << getvalue(substr(theHex,i,1)))
);
Show(theBinary);
