3.7 Procedures

Procedures contain sequences of commands in the SINGULAR language. They are used to extend the set of commands by user defined commands. In a SINGULAR session, procedures are defined by either typing them on the command line or by loading them from a library file with the LIB or load command (see Libraries). A procedure is invoked like normal built-in commands, i.e., by typing its name followed by the list of arguments in parentheses. The invocation then executes the sequence of commands constituting the procedure. All procedures defined in a SINGULAR session can be displayed by entering listvar(proc); .
