This formula converts a Hex string parameter (RefNumber) to a decimal value:

// Hex To Dec
numberVar x := len({?RefNumber});
numberVar base16 := 1;
numberVar value := 0;
numberVar decval := 0;
stringVar s;

while x > 0 do
(
    s := mid({?RefNumber},x,1);
    if s = "F" then
        decval := 15
    else if s = "E" then
        decval := 14
    else if s = "D" then
        decval := 13
    else if s = "C" then
        decval := 12
    else if s = "B" then
        decval := 11
    else if s = "A" then
        decval := 10
    else
        decval := cdbl(s);

    value := value + (base16 * decval);
    base16 := base16 * 16;
    x := x - 1;
);

value;
