Nice trick there, at first I thought it wouldn't work, but it does actually!

Konstantinos did well using ASCII, that's a good way to get rid of the switch statement.

PHP код:

stock SetCombination(&var, slot, value)
{
    new comb[11];
    format(comb, 11, "%010i", var);
    comb[9 - slot] = (1 <= value <= 9) ? 48 + value : 48;
    var = strval(comb);
    return 1;
}
stock GetCombination(var, slot)
{
    new comb[11];
    format(comb, 11, "%010i", var);
    if(48 <= (slot = comb[9 - slot]) <= 57) return slot - 48;
    return 0;
} 


It should work now.

Good job.
