Hey y'all,
I suspect that I'm struggling with something that has a *really*
straightforward alternative, but I don't do a lot of programming in perl (or
any other language, really), and I can't see it.
I've got a block of code that I'd like to run in a loop until a user enters
some desired input. My question is what control structure I should be using
for greatest efficiency and clarity? What I'm using now is something like
this:
while () {
if ($input = 'this') {
# Do some things.
last;
}
elsif ($input = 'that') {
# Do some other things.
last;
}
else {
print "The original directions again.\n";
chomp ($input = <STDIN>);
}
Keeping the conditional statement empty and using last gets the job done,
although I know it's not right (even if it is effective). Can someone nudge
me in the right direction?
-Owen.
