RE: Subfile question

["jt" <jt@xxxxxx>]

Mike,

As you said, these records are just left hanging because the SFLCTL format
doesn't clear the previous lines that the subfile displayed.

One way to deal with this is to display a record format, like your F-key
descriptions at the bottom, without using the OVERLAY keyword.  This will
clear the screen, then you can display the SFLCTL with or without the
subfile.

Another way I like to use is to display a line such as "(No records to
display)" instead of the subfile, if the subfile doesn't have any records.
Just add a record format to the DSPF with some text like this--positioned
somewhere over the top of the subfile.  Then in the RPG either set on the
SFLDSP indicator *or* display this format and set the indicator off,
depending.

Regards,

jt

Subject: Subfile question


Hi all.

    I have a subfile question.  I have a program that writes records to a
subfile.  One of the options of the subfile is to delete a record from the
subfile.  If a user uses this program and deletes all entries of the
subfile, the entries are still displayed on the screen.  There are no
subfile entries, and the subfile display indicator is set not to display the
subfile, but the records still appear on the screen.  The user can not take
any options against these records, and they are not loaded in the subfile.
This only occurs when there are records in the subfile and the user deletes
all of the records.  If all but 1 record are deleted, the subfile only
displays the remaining record.
    I believe this occurs because the records were on the screen and the
subfile is not displayed on the screen again because there are no records in
the subfile.  I believe that the records on the screen are just 'residual'
records left over from the previous transaction.  I have run into this same
situation many times before, but this particular application requires the
user to delete all of the records in the subfile more often than not.
    Does anyone have any ideas on how to correct this situation?

Thanks


Mike Silvers
