C-1.3.3 Avoiding unnecessary setting instructions
If you write branched programs in which some of the subroutines only show blocks of text, the
fact that the projectors are set to the appropriate magazine position each time the subroutine is
called even though it does not use the projectors, can sometimes be a nuisance.
This setting can be prevented by placing a SLIDE instruction which sets the projectors to the
magazine positions of the main loop in front of the LABEL definition of the particular subrou-
tine: this eliminates setting. The example program supplied uses this trick to demonstrate the
SCREEN instructions.
Example:
WAIT 3; With projector instructions
DARK AB;
JUMP START; Jump back to main loop
No projector instructions are used from this point on
SLIDE ABO; Magazine setting = main loop
LABEL SCRE; *** Subroutine SCREEN instructions ***
SHOW INTRO2;
WAIT 2.5;
SHOW SHOW; Without projector instructions
This programming trick can be used to speed up the execution of a subroutine which has a
purely text function by an amount equal to the time interval which would otherwise be required
to make the projector settings which are unnecessary in this case.

SLIDE <adrNN> Example: SLIDE A12
Select stated slide location - apertures (slide lifter) open automatically.
SELECT <adrNN> Example: SELECT A12
Select stated slide location - apertures (slide lifter) remain closed.
OPEN <adr> Example: OPEN A
Closed apertures open as soon as address projectors are ready.
