Here is a way to reduce memory usage:

PHP код:

CMD:commands(playerid) {
    new list[1500];
    strcat(list, ...); // you put tons of text into "list"
    ShowPlayerDialog(playerid, ..., list, ...);
}
/*
Now this is another way of doing things! And this way is faster too!
NOTE: you should use this only for constant texts i.e. strings/arrays that never change.
*/
CMD:commands(playerid) {
    static list[1500];
    if (list[0] == EOS) { // now this will only do the strcat part one time: first time when this callback is called
        strcat(list, ...); // you put tons of text into "list"
    }
    ShowPlayerDialog(playerid, ..., list, ...);
} 


In your case, if you have large constant arrays/strings which you use to display, just convert to "static".
