number(char("A"))

check out script.startProfile and script.stopprofile (see below).

on testScript () {
         script.startprofile(true);
         text = string.filledstring("something somewhere",1000);
         for i=1 to sizeOf(text) {
                 text[i];
                 «string.nthChar(text, i)
                 };«string.mid(text, i, 1);
         script.stopprofile(@scratchpad.profiletest);
         edit(@scratchpad.profiletest)};
testScript()
