What is tail call optimization?

TOP:
if (n < 2) return acc;
acc = n * acc;

...follow the label character by another character which can’t be used in a GOTO, then commenting your cmd script should not affect your cmd code.
The hack is to put lines of code after the character sequence “:;”. If you’re writing mostly one-liner scripts or, as may be the case, can write on...
