Even if there's no data to be returned from a procedure, each procedure should at least return a boolean to indicate when procedure execution failed, so callers can respond accordingly.


== Noncompliant Code Example

     D MyProc          PI
     D   param1                      10A   const
      /free
        // do work...
        return;  // Noncompliant
      /end-free
