RETURN

The RETURN statement transfers control of execution from a FUNCTION program block. It can also return values to the calling routine. (This statement can appear only within a FUNCTION program block.)

The RETURN statement can occur only in the definition of a function. This statement tells 4GL to exit from the function, and to return program control to the calling routine. (The calling routine is the MAIN, FUNCTION, or REPORT program block that contains the statement that invoked the function.)

You can use the RETURN statement in either of two ways:

Without values, to control the flow of program execution.

With a list of one or more values, to control the flow of program execution, and to return values to the calling statement.

If 4GL does not encounter a RETURN statement, it exits from the function after encountering the END FUNCTION keywords.

When the function is invoked by the CALL statement, an error results if the values listed in the RETURN statement and the variables listed in the RETURNING clause of the CALL statement differ in number, or are not of compatible data types.
