To get your project working, go into "edit project", then "node properties" for "?.hex" and change language tool to "pic C linker".
This allows you to use multiple files which are linked at the end.

Go to my tutorial at http://www.workingtechnologies.com/htpic/Hi-Tech_C_tutorial.htm and it will explain how to set up a project.

Hope this helps,
Regards,
Shane.

> MPLAB 5.00 doesn't appear to allow the .as file to be added as an
> extra node to the project, and if I add either the .as file or .obj
> filename to the 'additional command line options' section it will
> compile (and also assemble, in the case of a .as file), but DOESN'T
> generate a .hex file (no error message), and doesn't find the external
