SFLNXTCHG and Function Keys on Subfiles

I am writing a subfile which looks similar to the following.

Opt        Order    Qty    Reason    Notes
__        12345      6        __            Test Test Test
__        45656      8        __            Test To Test To

My program basically loads the subfile

Eg.           EXSR $WS01        (this formats the data and writes each
subfile record
                WRITE    S01C
                EXFMT    S01

Then I do READC S01 to determine subfile changes - the user may choose to
place a one in one or many of the option fields or select F4=List to prompt
on a reason code.

Has anyone got an example of how this is done.  I tried the SFLNXTCHG
indicator but in all the reading I have found it to be quite confusing and
am encountering multiple problems with not knowing which relative record
number I am at when selecting F4 etc.  Basically I am in a big mess.  I
think I have two separate problems here.  1)  I don't have the SFLNXTCHG
keyword processing correct in my RPG and 2)  I don't know how to process a
function key on a subfile.

All I want to do is be able to do an F4 on the reason and have the code
returned from a selection list to the correct subfile line selected from
and if there are any errors - eg the user enters in the wrong code then
that line is highlighted and not processed and the subfile is re-written
showing the errors and removing those items already processed.

Any help would be appreciated.
