Re: Subfile not working correctly after deletion of record

I do not see any read of your 2nd subfile.. something like "chain i
window1; " is missing in the loop inside your delete_record subroutine...

When you fill the subfile after a delete you would need to re-set the
marker for the data file at the first record of the subfile.

In other words, I believe you will want to save the file's key for RRN
#1 and then use that SavedKey as:
setll SavedKey FILE;
at the end of your delete routine. This will reset your reads to begin
at the same place and should refresh your display, minus the deleted
record(s).

Hello, I am a real Noobie! I have been spending my spare time trying to
learn how to program on the AS/400. I have purchased several books,
printed tons of IBM Redbook documents, and now, I am hoping someone here
at this forum can point out my error.

I have been writing and rewriting an example from one of the books I
purchased, "Subfiles in Free-Format RPG" BY Kevin Vandever. specifically
example sfl006rg, sfl006df. I have been modifying it for my purposes and
once i have a working copy, I would delete it and rewrite it taking a
different approach hoping the repetition would sink in. This is a simple
program that, when completed, would allow you to add display, delete, and
edit records. Each approach I would take in rewriting it would be to get
the basic view up and going and then add 1 function at a time. My last
approach was adding the delete function and for the life of my I cant
figure out why its not working. I have printed the sample code out and my
own code and have looked at them step by step but because of some of the
name changes, I have become completely lost. So, hopefully someone her
will have a laugh and show me what I am missing.

Problem: After I delete a record, the subfile doesn't show all the
records in the file, minus the one deleted, only a few of them and the
subfile will not load any records by pressing page-up or page-down. But,
if I add a new record, the subfile will start working again, showing all
records.

My mind is jumbled and I need someone to point me in the right
direction, Thanks for your time!

Garrett
