In Perl, if and while statements (and many others too) are used to control a block of code that may run many times, or may run only if a certain condition holds. This module not only introduces you to if and while, but also gives you some programming tips to help you come to grips with the increasingly complex structure that you'll be writing as your program gets longer.
This topic is presented on public courses Perl Programming, Perl bootcamp Examples from our training material
