Indirection Operator (FPScript)
Used to access data sets, functions and variables by using their names.
Syntax
$Expression$
The syntax of the indirection operator consists of the following elements:
Element |
Description |
|---|---|
Expression |
Any expression which returns a string. |
Remarks
The operator allows indirect access to any objects, e.g. a data set or a document, by using its path name.
You can use the above syntax at all positions in the code where an object name is permitted.
Formulas that use the indirection operator are recalculated every time they are updated. If you access a different formula using the indirection operator, this formula will be updated before each access to the data.
If no component is specified, the operator supplies an object reference, i.e. $"DataSet"$ is equivalent to DataSet As Object. If a component is specified, it supplies the component's value, i.e. $"DataSet.X"$ is equivalent to DataSet.X.
