PREFIX and display files

Hi there.

I am trying to use the PREFIX keyword on a file definition to put all the
fields in a DS, but the the compiler isn't in a very agreeable mood.

In my program:

FALFOFPANT CF E WORKSTN SFILE(LISTADO:RRN)
F INDDS(I)
F PREFIX('SCRN')

And then:
D SCRN E DS EXTNAME(ALFOFPANT) QUALIFIED

I am doing the same thing with my other files, and everything is working as
it should. But attempting to do so with ALFOFPANT results in a myriad of
errors.

Are display files compatible with the PREFIX keyword? I can't find nothing
that says otherwise in the documentation, but maybe I am missing
something...

Thanks,
Regards,

I.-
