i second that! i'm working on a very old script which has, for example, 130 lines of nested if-else blocks, and it goes down 6 levels. as if this wasn't complicated enough, it uses global variables.

always imagine yourself sitting in front of your code six months later trying to understand what it does. having to scroll up and down the whole time is exhausting.
there's the rule of 24 lines for a subroutine as a maximum. originally because that's the standard terminal height. some might say, nowadays you have big screens and big windows, but that dosn't help much, because then still your eyes have to move up and down, so that 24-rule (with exceptions of course) is still a good rule.
