The )set command is used to view or set system variables that control what messages are displayed, the type of output desired, the status of the history facility, the way FriCAS user functions are cached, and so on. Since this collection is very large, we will not discuss them here. Rather, we will show how the facility is used. We urge you to explore the )set options to familiarize yourself with how you can modify your FriCAS working environment. There is a HyperDoc version of this same facility available from the main HyperDoc menu.
The )set command is command-driven with a menu display. It is tree-structured. To see all top-level nodes, issue )set by itself.
Variables with values have them displayed near the right margin. Subtrees of selections have ... displayed in the value field. For example, there are many kinds of messages, so issue )set message to see the choices.
The current setting for the variable that displays computation timings:displaying whether computation times timings:displaying are displayed is visible in the menu displayed by the last command. To see more information, issue
)set message time
This shows that time printing is on now. To turn it off, issue
)set message time off
set message time
As noted above, not all settings have so many qualifiers. For example, to change the )quit command to being unprotected (that is, you will not be prompted for verification), you need only issue
)set quit unprotected
set quit unprotected
