Variables

A LogicPro Variable is the name tag given to a piece of data

used by various execution elements of the Program. Variables

are both physical I/O and internally represented data.

LogicPro uses several types of Variables, including:

• Project Variables

• Resource Variables

• Program Variables

Naming Conventions

When naming Variables try to be as descriptive as possible

especially if there are more than a few Variables in the

Program. For example, Go_Light_On will prove more useful

a name than Variable_1.

Variables may be up to 28 characters long.

lnitial Value—When a logic program is first run all of

the variables are set equal to the initial values specified

when the variables are declared or created. If an initial

value is not explicitly entered in the Add Variable

dialog box, the variable is set equal to zero. Unless a

variable is set as retentive, it is set equal to its intitial

value each time the logic program is run.
