Procedure_Return

See Also: End_Procedure, Function_Return, Procedure

Purpose

To return execution from a procedure.

Some existing DataFlex procedures return values. This technique is now discouraged. You should not create any new procedures that return values (use functions for this purpose).

Syntax

Procedure_Return

or, legacy syntax

Procedure_Return  [ {returnValue} ]

What It Does

The Procedure_Return command is used to terminate a procedure. This command is optional and is only needed if you wish to return from a procedure before the End_Procedure command is encountered.

Example

Procedure RunLoop integer iCounter

    Integer iCount

    String sName

    For iCount from 1 to iCounter

         Get TheName to sName

         // if we run out of names…end the procedure  

         If (sName="") Procedure_Return

         Send ShowTheName sName

    Loop

    // if the loop is completed, End_Procedure will terminate the procedure call.

End_Procedure

Notes

• There may be as many Procedure_Return commands as necessary in the body of the procedure.

• Some procedures return values. If a procedure returns a value the return value is passed as a parameter of this command. returnValue can be a constant, variable or expression.
