G. The PAUSE Statement
The PAUSE statement is a semi.automat ic form of the PR INT statement . It displays the
various items in its associated list for a fixed and brief t ime period. The us .. r is thus freed
from the burden of prodding SHARP to co nt inue by pressing ENTER. Think of the PAUSE as a
PR INT statement followed by a countdown. Whern the countdown is over the program continues.
The formats of the PAUSE statement are identical to those of the PRINT statement. All of
the various techniques which we have d iscussed for the PR INT statement are applicable to the
PAUSE statement. although the resulting output will. of course, vary slightly. To illustrate o ne
use of the PAUSE statement, let's re.write our mus.ical scale program :
