Sysutils is a unit in the Free Pascal and Delphi programming languages that provides various utility functions and types for system-level operations. It includes features for file handling, string manipulation, date and time functions, and memory management. Additionally, sysutils offers exception handling capabilities and supports different data types, making it essential for writing robust applications. Overall, it simplifies many common programming tasks related to system operations.
