— THE
RUN/STOP KEY
(2ed) GS — THE
PAUSE KEY SEQUENCE
— Tre Run/Srop Key
Note that when you're out of "learn" mode and press
, the program
pointer begins stepping through program memory starting from its
current location. If you want to start at the first program step (step 00), you
need to press
before pressing IRA). (You can position the program
pointer at any other location you'd like to start at with the
key —
discussed later.)
[2nd]
— Tue Pause Key SEQUENCE
you enter it into your program while in learn" mode. While a program is
running and the program pointer comes to a [2a] HMM instruction, it stops
the program for about % of a second and displays whatever result is in
the display register at that point. Then, it continues on to the next step.
The
QB key sequence lets you get a quick look at a program result,
without stopping the action. This sequence is especially handy when
used in repetitive programs (or "loops'') — letting'you watch the
changing results of continuing calculations. You can watch your money
grow" in a compound interest account as the months go by, or watch a
function go to a 'limit', etc, If you'd like a pause that's longer than % of a
second, you can just add additional 2s) MIB key sequences, and keep
things in the display % of a second longer for each pause sequence you
add. (Keep in mind, however, that each
MM key sequence you add
to a program will use up one of your 50 allowed program steps.)
