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:
