 User Level Required: interpreter

 Command Syntax:





)set





)set label1 [... labelN]





)set label1 [... labelN] newValue





 Command Description:

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.

be prompted for verification), you need only issue
