automatic refresh

Folks,

I'm having a problem with automatic refresh of a display.
The standard way of doing this is to use the INVITE keyword
on the DDS (testinvd) for the display file:

     A                                      DSPSIZ(24 80)
     A                                      CA03
     A          R DUMMY                     ASSUME
     A                                  1  2 ' '
     A          R SCREEN       OVERLAY
     A                                      INVITE
     A                                  1 17' JCR- TEST REFRESH WAIT'
     A            COUNT          3S 0B  4  4
     A                                 10 13'Compile this dspf with the
WAITRCD-
     A                                       value set to the number'
     A                                 11 13'of seconds you wish to delay.'

then the following RPG ILE program counts up the COUNT with automatic
refresh of the display every WAITRCD seconds until you hit PFKEY 3:

     Ftestinvd  cf   e             workstn
     F                                     maxdev(*file)
     F                                     devid(pgmdev)
     C                   dow       not *inkc
     C                   add       1             count
     C                   write     screen
     C                   read      testinvd                             9999
     C   kc              leave
     C                   enddo
     C                   eval      *inlr=*on


this works fine for a "normal" display, but does NOT work for
the async console. Probably because the maxdev parm
having no effect for the console or some such stupid thing.

Second problem:
an RPG/400 version of the above.

Third problem:
How to avoid the erasure of the screen when the
RPG program returns.

TIA
