Text feild variables!

[pyro.699]

ok, i made a text feild

<input tabindex="1" name="A" type="text" value="XXXX" size="7" maxlength="4" />

and what i want to do as add each character in the "text feild" to a variable,
since default it XXXX i would like the out put to be something like this

$first = X;
$second = X;
$third = X;
$fourth = X;

like each digit a separate variable.

it goes from A - F so 48ish variables would be put out....

(its not always going to be 4x X's)
