Lists and Arrays,g scalar variables into which we can store numbers and strings is nice—this allows us to write programs to manipulate data. However, scalars are somewhat limited since they can only contain a single value.

Files and Data,e can do is ask the user for input using ‹STDIN› and print data on the screen using print (). Pretty simple stuff, yes—but these two ideas actually form the basis of a great deal of the file handling you’ll be doing in Perl.

So, if we’re going to write programs that do more than say hello to us, we’re going to need to know how to perform computations, or operations on our data.

It would be tedious to write out the code for each of these little processes every time we need to use one, and maintaining each code segment would be horrific: if there’s a bug in the way we’ve coded the activi

Perl also has many built-in string operators (such as the string concatenation operator . and the string replication operator x) and string functions. In this chapter we will explore several
