Usage: **set** *param*, *value*

**set**

Set *param* to *value*.

In the first form *param* must a string, and *value* must be of the appropriate
type for the parameter, e.g. a number, boolean, or array.

In the second form, we give a list of parameters that can be supplied.

Examples:
---------
    set                  // lists set parameters
    set "autoeval" false // set autoeval off
    set "width" 100      // set terminal width 100
