Packages are sets of data types and routines that are stored as resources and brought into memory only when needed. They serve as extensions to the Toolbox and Operating System, for the most part performing less common operations such as:
• Standard File Package - standard interface for opening and closing files.
• Disk Initialization Package - initializes and names new disks.
• International Utilities Package - accesses country dependent information.
• Binary-Decimal Conversion Package - converts strings to integers.
• Floating Point Package - supports extended precision arithmetic.
• Transcendental Functions Package - the math library.
