u To display detailed information about a physical constant
1. Tap the physical constant value whose information you want to view so it is highlighted.
2. Tap F.
u To assign a physical constant to a variable
1. Tap the physical constant value you want to assign to the variable so it is highlighted.
2. Tap Edit - Store or l.
3. On the dialog box that appears, enter a variable name and then tap [OK].
• This assigns the physical constant you selected in step 1 of this procedure
to the variable whose name you input above.
