Yan-Bing Ho,Wun-She Yap,Kok-Chin Khorhaving scalar variables into which we can store numbers and strings is nice—this allows us to write programs to manipulate data. However, because they can contain only a single value, scalars are somewhat limited.

Seung-Jae Yoo,Jeong-Mo Yang,Hwan-Seok Yange 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 do in Perl.

Ji-Yun Seo,Yun-Hong Noh,Do-Un Jeonge looked at hashes in Chapter 5, we found that hash values are scalars as well. As a result, in our exploration of Perl so far, we have not yet been able to create arrays of arrays (also known as .) or other, more complex data types.

Georges El-Hajal,Roy Abi Zeid Daou,Yves DucqMost of the programs we’ve seen so far have had a very simple structure—they’ve done one statement after another in turn. If we use boxes to represent statements, our programs would look like this:

Lecture Notes in Electrical EngineeringWe have talked about two types of data: scalars and arrays. Scalars are single pieces of information, while arrays are single variables containing many different values.
