5.10.2Setup and syntax of conditions

General

A condition consists of at least one operation that, in return, comprises operators and one or two operands.

The logical connection of the operands based on theoperators yields a Boolean result either as TRUE or 1, or as UNTRUE or 0.

Operands can be:

●Constants,

●Parameters,

●Variables,

●Controls, or

●fixed numeric values and texts (texts are output in between inverted commas)

.

An operand can also be an operation in parenthesis.

Syntax

Variables must be set in between $ signs, Constants and Parameters in between %% signs.

If you want to use Controls, please be careful to add a corresponding reference (see Section 5.9.2, "References to Controls").

	Operators	No. of	Example	Description
