Now that you know all about Perl's control structures, you're probablywondering which one to use when. Well, this section will try to clear thatdilemma up for you. * If you have a set of statements that need to be executed a number oftimes until a certain condition is met, but you have no idea what thatnumber is, the "while" and "until" loops are a good bet. * If you have a set of statements that need to be executed at least once,the "do-while" and "do-until" loops are the ones to go with. * If you need to execute a set of statements a specific number of times,pick the "for" loop and don't think twice! * If you need to process every element of an array, go with the "foreach"loop. Next time, we'll be teaching you a little more about array variables, andsome of Perl's more interesting array functions; we'll also take a look atPerl's file manipulation capabilities. What will you do until then? Well, they're bound to be showing re-runs of"Friends" on your local cable channel... This article copyright Melonfire 2000. All rights reserved.
