Researchers are using Perl for various scientific computations, such as biological data analysis (Bioinformatics) and other applications. By using Perl, you can quickly write programs which will run on a variety of computer platforms. If you are familiar with Perl, you can also edit programs written by other researchers or third-party providers.

Perl has powerful text processing and I/O capabilities, which you can easily use with the operators and functions built into the Perl language. You can also take advantage of Perl's numerous library extensions, which implement a wide variety of useful tools.

This class will provide an introduction to the Perl programming language. We will explore the elements of the language through interactive examples.
