Call custom functions (QuickFunctions)

Calling a custom QuickFunction differs slightly from calling a predefined standard function:

• The keyword CALL must precede the QuickFunction name.

• Results returned by QuickFunctions are always optional; you can use them, but you do not have to.

Call a QuickFunction that does not return a result

• Use the function name (and parameters, if any) preceded by the keyword CALL in a statement. For example:

  CALL QuickFunctionName(Parameters);

Call a QuickFunction that returns a result

• Do either of the following:

  • Call the QuickFunction as if it did not return a result (see the preceding procedure).

  • Use the function name (and parameters, if any) preceded by the keyword CALL anywhere in a script where you could use a literal value or a tagname of the relevant data type. For example, in a value assignment:

    ResultsTagname = CALL QuickFunctionName(Parameters);

    Or in a nested function call, using it as a parameter for a standard function:

    OtherStandardFunction(CALL FunctionName(Parameters));

Note: You cannot nest QuickFunction calls so that a QuickFunction is used as a parameter for another QuickFunction. For example, Call QF1(Call QF2()); is not a valid statement.
