Is there an API that will allow me to run a program by passing a file name and having the OS run the program based on the current file association?

This is for Fox 2.6 and would love something that would work in 3.11/9x/NT is possible. Something like...

RunProg('MyFile.Doc')

and it would run Word and word would open myfile.doc... Or, it would run word perfect, if that was what was associated?

Thanks,
