User Level Required: development
This command is used by FriCAS system developers to have single expressions evaluated by the Common Lisp system on which FriCAS is built. The lispExpression is read by the Common Lisp reader and evaluated. If this expression is not complete (unbalanced parentheses, say), the reader will wait until a complete expression is entered.
Since this command is only useful for evaluating single expressions, the )fin command may be used to drop out of FriCAS into Common Lisp.
