Exiting Processing Blocks

Processing blocks can be exited implicitly using:

• regular exiting

or program-driven, using:

• RETURN

• EXIT

• CHECK

• STOP

• CHECK SELECT-OPTIONS (obsolete, for logical databases only)

• REJECT (obsolete, for logical databases only)

The subsequent program flow depends on the type of processing block.

In addition to the statements described here, statements that call other units without returning to the caller after the call is made, also terminate their processing block. These include:

• LEAVE $[TO$] SCREEN

• LEAVE LIST-PROCESSING

• LEAVE TO TRANSACTION

• SUBMIT without AND RETURN

Messages and raised exceptions can also exit processing blocks.

Only use RETURN to exit procedures

Notes

• Exiting a procedure using RETURN, EXIT or CHECK is the error-free termination of the procedure. Formal parameters for which the pass by value is defined are not passed to the assigned actual parameters only if the procedure terminates after an error (an exception is raised or a message is sent).

• The statements for exiting programs are not recommended inside procedures. They are not allowed in contexts like unit tests or during update and lead to exceptions if a procedure is called from such a context.
