Evaluate (Magic xpa 4.x)
This operation lets you execute a function without having to pass a variable that will receive the result. For example, you can use this with the Delay function or the INIPut function where the result is usually not useful to you as a programmer.
Inside the expression, you can combine as many functions as required. When you do so, the Return code of the operation evaluates to True only if all the functions are successful.
The Evaluation operation properties are:
|
Expression
|
The expression number to be evaluated is required. Zoom to the Expression Editor to select or define the function you want.
|
|
Result
|
This property is optional. It gives the user the ability to select any kind of variable from the task’s Variable list. If the called program has a return value, this value will be entered into this variable.
|
|
Condition (Cnd)
|
The Cnd property contains a logical condition that determines whether the operation execution occurs or is bypassed.
The possible values are:
Yes (the default) – The operation is always executed.
No – The operation is always skipped.
Expression number – Zoom from the Expression field to define an expression that returns True or False. The operation will be executed according to this expression.
