This is inefficient but try to do something like this.

pawn Код:

new a = random(3);
    strdel(word, a, random(5));
    strins(word, "...", a);

Instead of the whole text work on each words. And I don't know how to work on each words. Maybe use sscanf() to get all the words and store them separately.
