5 General interactive commands

Following are some commands useful in an interactive session:

• quit/bye: The only two ways to quit from the interpreter. Politer (more civlized) of the two commands is more recommended! Typing Ctrl-D will exit the interpreter after number of trials given by the environment variable FUSSY_INGNOREEOF (see Section Environment variables) and typing Ctrl-C will attempt to teach a thing or two about life!
• setfmt: Set the system parameter ’fmt’ used as the default format for printing numbers.
• warranty: Prints the warranty information.
