Description
This command changes the current scale.

(option `c' the default), or indicate a location which will become the new
screen center point (option `n'), or opt to have the origin point (0 0 0)
located at the lower-left corner of the screen (option `l') or in the middle
of the screen (option `m').  Specify the new scale.  If you selected option
`n' you will be prompted to indicate the current location of the new center
point.

Using METERS, the valid scales are 1:0.01 up to 1:100,000.  Using FEET, the
valid scales are 10' up to 0.0012" (10.000' up to 0.0001').
