Required syntax for expressions and scripts

The syntax in scripts is similar to the algebraic syntax of a calculator. Most statements are presented using the following form:

a = (b - c) / (2 + x) * xyz;

This statement places the value of the expression to the right of the equal sign (=) in the variable location named "a."

• A single entity must appear to the left of the assignment

  operator =.

• The operands in an expression can be constants or variables.

• Statements must end with a semicolon (;).

Entities can be concatenated by using the plus (+) operator. For example, if a data change script such as the one below is created, each time the value of "Number" changes, the indirect entity "Setpoint" changes accordingly:

Number=1;

Setpoint = "Setpoint" + Text(Number, "#");

Where the result is "Setpoint1."
