Some useful perl control structures:
do { statements; } while someexpression;
do { statements; } until someexpression;
while (someexpression) { statements; } --or-- statement while
someexpression;
until (someexpression) { statements; } --or-- statement until
someexpression;
unless (someexpression) { statements; } --or-- statement unless
someexpression; --or-- someexpression || statement;
if (someexpression) { statements; } --or-- statement if someexpression
--or-- someexpression && statement;
if (someexpression) { statements; } elsif (anotherexpression) { statements;
} else { statements; }
for ( initialexpression; testtocontinueexpression;
executeatendofloopstatement ) { statements; }
foreach $somescalar ( @somelist ) { statements; }

yet to use them, only using the foreach loop and if else stmts.
