PERL4 is an interpreted language that can be regarded as a cross between C, Unix shell, sed and awk. It is a C-based language which can also deal directly with Unix commands and file system and easily do string processing matching.

In this course, we will concentrate not on using PERL in systems programming, but in using PERL for CGI programming, i.e. implementing programs activated from Web pages.

In general, we use PERL for tedious high level things which can take a long time to program but not much execution time. For computationally intense programs, we would use a compiled language such as C.

Our first lecture on Perl will show a series of small programming examples from Chapter 1 of the Learning Perl book, designed to illustrate the main features of the language. Later we will cover each topic in more detail.
