Option 1. Tools.. contains functions used to operate on units (discussed later).

Options 3. Length.. through 17.Viscosity.. contain menus with a number of

units for each of the quantities described. For example, selecting option 8.

Force.. shows the following units menu:

The user will recognize most of these units (some, e.g., dyne, are not used

very often nowadays) from his or her physics classes: N = newtons, dyn =

dynes, gf = grams – force (to distinguish from gram-mass, or plainly gram, a

unit of mass), kip = kilo-poundal (1000 pounds), lbf = pound-force (to

distinguish from pound-mass), pdl = poundal.

To attach a unit object to a number, the number must be followed by an

underscore. Thus, a force of 5 N will be entered as 5_N.

For extensive operations with units SOFT menus provide a more convenient

way of attaching units. Change system flag 117 to SOFT menus (see

Chapter 1), and use the keystroke combination ‚Û to get the following

menus. Press L to move to the next menu page.
