In reading the description of Execute() in the AmigaDOS Developer's Manual,
the bit about the filehandles you pass to it isn't clear. If I want to
do the equivalent of "foo >nil: <nil:" I'm opening a filehandle nilfh to
NIL: and doing an Execute("foo", nilfh, nilfh).

I know you can put the redirection in the string itself, but the string
to be executed is variable.

1. Can I use the same MODE_NEWFILE handle for both input and output handles?
2. Will the handles be closed when Execute returns or can I leave them
   open and re-use them for each call?
