4.17 proc

Procedures are sequences of SINGULAR commands in a special format. They are used to extend the set of SINGULAR commands with user defined commands. Once a procedure is defined it can be used as any other SINGULAR command. Procedures may be defined by either typing them on the command line or by loading them from a file. For a detailed description on the concept of procedures in SINGULAR see Procedures. A file containing procedure definitions which comply with certain syntax rules is called a library. Such a file is loaded using the command LIB. For more information on libraries see Libraries.
