The %RO utility writes M source code for one or more routines to a sequential device such as, a disk file or a printer. %RO writes M source code in a format that can be used as input to the GT.M utility MUPIP CONVERT.

%RO uses %RSEL to select routines. For more information, refer to the section on %RSEL in this chapter.

%RO writes the routines in alphabetical order to the specified device. %RO displays the name of each routine as it writes the routine to the device.
