6. HOW
TO
USE EACH FUNCTION
AIIELSEC-A
[Explanation]
If the designated head step is in the middle of an instruction, processing
is executed assuming that the head step
of the instruction has been
designated.
(Example) When step 106 is designated in the example on the previous
page, steps
104
and after are displayed.
When the ACPU is
in
the RUN state, processing takes longer than in the
STOP state. Therefore, wait until an instruction to be read is displayed.
(The processing time is proportional to the number of steps in a program.)
If the [GO] key is pressed after pressing the [STEP NUMBER], the step
number, and the [GO] keys, the screen is scrolled up.
