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); .
