Hello,
For locating the correct record, what you present is sufficient if your key is alpha (which is your case as per your example). Just make sure than the user input is left align (Obbbbbb not bbbbbbO).
Where you will get some surprises is in the subfile processing.
- If you use a load all subfile and you load it from the record requested, you won't be able to do a page up because the preceding records were not loaded.
- If there is no records (user entered ZZZ), you have to display an empty subfile
- if there is no entry starting with "O", what record do you want to see first (the last starting with "N" or the first starting with "P"
- ect.
What you should aim for is for your subfile to behave like PDM does.
We do that at our shop and we use exclusively page at a time subfile to achieve this
Hope this help

Objet : Subfile question - Position To functionality
Hello all,
Question for the group. I have the need to add "position to" functionality to a subfile program. In this scenario, my subfile has one field which is
a bin location in a warehouse. The one field could look something like
"OVER-1A". I want the user to be able to key in just the letter "O" in a field on the subfile screen and have the subfile display starting with the records that begin with "O" and going from there. Is it just as simple as doing a SETLL with the "O" as the key and it will read the records from there on or is there more to it than that? Any info is as always
appreciated. Thanks!
Bill
