Operands in ST

Within logi.CAD 3, an operand may be one of the following constructs:

• a →literal

• a →variable or an →output variable of a →function block instance

• a →call of a →function with return value

• a →call of a →method with return value

• another →expression

You need operands, if you enter other elements within ST, e.g. when entering →assignment.
