Programming 83
Other Programming Functions
(HOLD) DISP: takes a number that represents 1/5 of a second. DISP5 is
thus one second.
(HOLD) STOP: Stops the execution of the program. This instruction should be
placed at the end of every program.
(HOLD) R/S: Pauses the program execution and returns to the normal system.
You can then resume program execution by pressing again. This can be used,
for example, when you need to enter a number.
(HOLD) DSE ( ) and (HOLD) ISG ( ), followed by 1 digit (0
to 9): Loop control function. Place a number of the form ccccc.eeeii where cccc is the counter,
eee is the end value for the counter and ii is the increment in variable 1. For example, DSE 1
will decrement the counter part of the variable by ii (if ii is 0, it decrements by 1) and, if cccc
is less or equal to eee , it will skip the next instruction (usually a GOTO).
For example, to loop from 0 to 50, incrementing by 3 each loop, use 0.05003 as start the
value and the ISG instruction. The following program will loop from 0-50, incrementing by 3
each loop and pause shortly at each loop to show the counter. At the end, it will leave 12
with a blinking cursor. Once in Program mode, select an unused program number and press:
.05003:$1
