Yes, subroutines. Subs are one of the most powerful ways to tame code complexity; without them you quickly end up with huge, monolithic scripts that are impossible to read, modify, or debug. Read `perlsub`, and soon you'll be sub genius. :-) the lowliest monk	[reply] [d/l]

Although I like the overall syntax and simplicity of the pseudocode it does bring two things to my attention. 1) You need to predeclare the variables at the top of the script otherwise when working in subs you'll get blasted with errrors, especially under strict. 2) Not being one of the "sub geniuses" myself, I don't think you can get by using last; inside of a sub routine and at the moment I can't think of a different way to go about doing that.

If you look at the original sketch I posted, you'll see that there are two `last` statements, one for each of the two loops; they both occur in the main body of the program. But most of the script's work is handled by subroutines like `ask_next_question()`, `check_answer()`, `update_score()`, etc. the lowliest monk	[reply] [d/l] [select]
