Oddly enough, the SAA CUA standard for scrolling is F7/F8!  I think Fabrizio
is asking how to define the DDS so that the PAGExx keys work.  Look up the
manual on Display Programming.  It will describe how to set up subfiles.
Basically there are two ways:
1) SFLSIZ = SFLPAG --- there is only one page in the subfile.  The
programmer uses the indicators on the PAGEUP/PAGEDN keys to clear the
subfile, position the file pointer and load the subfile.
2) SFLSIZ > SFLPAG -- there can be multiple pages in the subfile.  The
system handles the PAGEUP/PAGEDN keys while the user is within the pages
already loaded, and the programmer handles the PAGExx keys to load pages
beyond that range.

Hope this helps!
