Tell the computer the size of the block.

When you enter this screen, the "Width" label is highlighted, so you can
start keying in the width. 

For example, if your block is 7 inches wide, touch the number 7.  See
how the number appears next to Width?

Note: the inches are shown in decimals. Half an inch should be entered
as .50, a quarter inch as .25, three fourths of an inch as .75, a third of an
inch as .33. A 7 and a half inch block would be entered as 7.50  Don't
forget the "."! If you enter 750, it will make the block 750 inches wide.

If you make a mistake, touch [Clear].

When you have entered the size, touch [Enter]. Now the other dimension
will be highlighted. Key in the number for it.

If you've entered both height and width but realize you've made a
mistake, just select the dimension you want to change and enter the
correct size.

When you have entered both dimensions, a [Continue] button will 
appear. However, the computer will not accept a block where one of the 
dimensions is only 1".  You cannot continue with a block that small.

Touch [Continue] to go on to the next step.
