File Operations

Although missing from the original Pascal language, extensive and practical file operations can be performed in Borland Pascal as well as FreePascal. Most of these operations have parallel operations in more popular languages such as C, C++ and Java.

This chapter first explains what files are, and what kind of file are available in the language. Then, this chapter introduces the built-in functions and procedures that a programmer can use to operate on files. The last portion of this chapter explains some of the most popular and useful algorithms related to files and data processing.
