Overall User Source Considerations

You cannot specify Neither (N) type parameters for this function type. The following table shows the allowed parameters.

No action diagram, device design, or function options are associated with this function type.

Although the EXCUSRSRC function provides flexibility, for ease of maintenance, you should use action diagram programming whenever possible.

The HLL source is held in the source member that CA 2E assigns. CA 2E provides a source member name which you can override with the name of the source member that you want to call. Change the source name at the Edit Function Details panel.

The source member must reside in the appropriate source file. The source file must be in the library list of any job that generates source for CA 2E functions that call the EXCUSRSRC function. The files are as follows:

• For RPG functions, the source member must reside in the file QRPGSRC.
• For COBOL functions, the source member must reside in the file QCBLSRC or QLBLSRC.

Parameters must be passed in accordance with the instance code that you generate in the EXCUSRSRC function. To define parameters for the user source:

• Define the EXCUSRSRC function and optionally attach it to an existing access path or else specify *NONE for the access path.
• Type P next to the function from the Edit Functions panel and define the parameters accordingly.

For more information on defining parameters, refer to this module, in the chapter, "Modifying Function Parameters."
