This situation gives us the opportunity of inviting you to perform a new experiment:
Try replacing the instruction SLIDE A10 in line 8 by the instruction SELECT A10. As ex-
pected, the projector goes to magazine location 10 but does not show the slide. The slide
cannot be viewed until you have inserted the instruction OPEN A in line 10 for example.
Naturally, the OPEN instruction has a counterpart - the CLOSE instruction - which allows you
to return the projected slide to the magazine gate and set the slide lifter to the SELECT posi-
tion. Try inserting this instruction as step 12 in your program after a waiting time of 5 seconds.
Your program now looks as follows:
LIGHT A
SLIDE A1
WAIT 5
SLIDE A5
WAIT 5
SLIDE A8
WAIT 10
SELECT A10<— modified
WAIT 5
OPEN A <— added
WAIT 5 <— ditto
CLOSE A <— ditto
Now is the time to take a look at the program in its entirety - until now you have only tested
individual steps. You use the F5 function (RUN SEQUENCE) to do this. This function starts
your program at the program step which is on the input line. If you want to see the entire
program, first use the HOME key to go to the beginning of the program and press F5 to run
it..cp255

When the program is running you should pay special attention to program steps 8 to 12 in order
to observe the special features of the SELECT, OPEN and CLOSE instructions described in the
paragraph on the previous page.
B-1.4 Making an attractive impression
Let’s assume that slide No. 5 in the program on the previous page contains information which
you particularly wish to draw to the attention of the recipient. In this case you might well try and
ook for a visual effect and this gives us the chance to introduce the FLASH instruct
n .
For instance, you might want to make the projector lamp flash 5 times at a rate of 0.1 s. Neverthel
ss, the slide is still to be shown for 5 seconds. This can be calculated as foll
s :
5 x 0.1 s = 0.5 s (sum of lit durati
n s ) 5 x 0.1 s = 0.5 s (sum of unlit durati
n s ) — — — — —
