RE: SFLINZ (or) SFLCLR

[Bruce Guetzkow <bguetzkow@xxxxxxxxxxxxx>]

We use SFLCLR and an expanding subfile.  If the first page fills up, the user 
can roll to get another page.  When the user is finished keying the text, we 
can update the DB records for subfile records that are not blank, delete DB 
records for blank subfile records and add DB records for RRNs in the subfile 
with no corresponding DB record.

Using SFLINZ, you limit the user to the number of records that the subfile was 
initialized for.

And you're right...subfiles are neat!  (If only they could be keyed...)

Subject:        SFLINZ (or) SFLCLR

Hello all;
As a new AS400 person I have a quick question that requires your
opinions:

On Subfiles (they're very neat!) If I have a file that just contains a
Key say.. account number.  eg) 12345 and then a sequencing part of the
key..say eg)  001 002 003....etc
Ergo--
12345001 Hi Billy here is text line 1
12345002 Here is text line number 2
12345003 thisr line
etc.....etc.....

If I am updating and adding to this file using an interactive screen
job, should I use the SFLINZ and initialize my subfile with blank
records then CHAIN back to it and update the blank records with existing
text records.
(OR)
Would you recommend using the SFLCLR and then reading the existing text
and WRITING them to the subfile and then WRITING some blank records
after your done reading the existing records, to provide the user with
some useable keying text lines.

Advice appreciated.
