Pausing
During
Program
Execution
An
instruction
executed
in
a
program
interrupts
program
execution
to
display
results
momentarily
before
execution
is
resumed.
The
length
of
the
pause
is
about
1
second,
but
you
can
use
more
than
one
consecutive
instruction
to
lengthen
the
pause
duration.
To
see
how
can
be
used
in
a
program,
we’ll
modify
the
cylinder
volume
program
in
the
previous
example.
In
the
new
program
the
area
of
the
base
will
be
briefly
displayed
before
the
volume
is
calculated.
This
example
will
also
show
how
different
programming
approaches
can
be
taken
to
solve
the
same
problem.
