"do-nothing"
FOR
...
NEXT loop acts
as
a simple delay loop. Looping
from 1 to 10 after each character print approximately doubles the processing
time.
Vou
can change the delay time
just
by changing the end index value
(in
this
case
10).
Optionally add the index variable 1 to the NEXT in line 140. Using index
names
on
NEXT statements
is
a good idea, especially when vou have nested
FOR
...
NEXT loops.
