How not to write a loop

[Claes Thornberg]

Keywords:

A simple recommendation for all hackers(?) writing programs. Even
though your program is 'running' on the machine you are using now,
please think a little about compatibility. When giving away programs,
which I encourage you all to do, there may be a lot of machine
dependent bugs not doing this, and it is frustrating trying to locate
these in a program you haven't written yourself, especially when you
know the program worked when you got it. And thinking of simple things
like not using real variables in for-loops isn't that hard, I think I
was told not to do this in my very first programming class. So all you
hackers using obscure features that works on only a few machines,
please spare us the time it takes to locate bugs that shouldn't exist.

Yours in hacking,
