AS/400 - QUICK Control Function keys F7 & F8

[Daniel Mielke]

Hello all,

I'm looking to control the block transfer of records in a cluster for a
display screen.

The following screen displays the races for a specified Rat's Ratlets.

RATRACES                       Rat Races Screen

               Rat number: 123456    Rat Name:  Slick Rat

Ratlet-no      Ratlet      Race number    Earnings      Final position
1                Mini rat           456             $3,450.00          1
7                Super rat         466             $    70.00          5
13              Slow rat           542             $      0.00         16


COMMAND ===>________________________________

If there were additional races for Rat 123456, F8 or [ENTER] would list the
next cluster of RAT-RACES.

However, since there are no more races, the F8 or [ENTER] clears the list
and returns to the command in find mode.  The same occurs for [F7] when the
user is at the initial list of races.

How do I control these function keys such that the user may scroll through
the existing records stopping at both the end and the beginning without
clearing the screen?

Special thanks to Chuck Reinke for the use of the Rat/Ratlets analogy
