Re: Subfile Positioning Question

["Booth Martin" <booth@xxxxxxxxxxxx>]

I am wondering what would happen if you blanked the User ID field after you
use it to do the positioning?  Are you doing page-at-a-time, or load-all?

Subject: Subfile Positioning Question
 
Hi
I have a subfile. Fields are 'Option'  and 'User-ID'.  In the Control also I
have the same fields. Now my question is about positioning cursor in the
subfile. User can enter User-id in the control for 'Position-to'. I am using
SFLRCDNBR to do that and that is fine. After positioning, if I just press
Page Up or Page down, and then press ENTER, the list is going back to the 
User_iD' it was positioned to last time. I know why it is doing that. But I
don't want this to happen. I want the list not to change the page with just
pressing ENTER.
 
I also though of using SFLCSRRRN, but since the screen also has input fields
in Control, and the cursor stays on control field every time I do EXFMT, it
is not going to return the RRN of the first record. To do that each time I
have to position the cursor to the first subfile record, WRITE the screen,
get the RRN, and then again move the cursor back to Control and then EXFMT.
But this way of doing this will make my program very complex since I also
have validation checks on Control and Subfile fields and if there is any
input-error, I am already positioning cursor there.
 
Please help.
 
Thanks
Amitava
