Decision making functions are explained in more detail below. These functions check a
condition and jump to a specified sequence if the condition is true. The sequence called must
be in memory. A sequence call is a one-way jump. A sequence can jump to itself, or to any of
the other five sequences currently in memory. Use of these features is explained under the
specific
softkey
descriptions
Decision Making Functions
Decision
makiug
fimctions jump to a
softkey
location, not to a specmc sequence
title
Limit test, loop counter, and do sequence commands jump to any sequence residing in the
specilled sequence position (1 through 6). These commands do not jump to a
specific
sequence
title. Whatever sequence is in the selected softkey position, will run when these commands are
executed.
Having a sequence jump to itself
A decision making command can jump to the sequence it is in. When this occurs, the sequence
starts over and
all
commands in the sequence are repeated. This is used a great deal in
conjunction with loop counter commands. See the loop counter description below.
Tl’L
input decision making
TTL
input from a peripheral connected to the parallel port (in the GPIO mode) can be used in a
decision making function. Refer to “The GPIO Mode” earlier in this section.
Limit test decision making
A sequence can jump to another sequence or start over depending
on
the result of a lhnit
