Subfiles have a 9999 record size limit.  Either modify the program to only load 9999 max or change design to a page at a time subfile.  Terrible for performance to load so many at once anyway.

The basic idea is that no user should be expected to have to scroll through 500 screens to get to a subfile record, so there shouldn't be a need for as many as 9999 subfile records. (A subfile with 20 rows per page needs 500 pages for 10000 records.)

The limit is never likely to be increased by IBM, so Gary's recommended page-at-a-time subfile style is good whenever more than a couple hundred subfile records are expected.

I don't write much interactive green-screen code any more, but when I did, I had gotten away from "all at once" subfiles completely.  

I just had a good page-at-a-time program template that I used whenever I needed a subfile program.

You can find the same template in Kevin Vandever's book "Subfiles in RPG IV : Rules, Examples, Techniques, and Other Cool Stuff".  Kevin also recently released an updated version of the book called "Subfiles in Free-Format RPG: Rules, Examples, Techniques, and Other Cool Stuff".  I also used Kevin's book as a textbook when I taught subfile programming - it really is a great resource.

Both are available from the MC Press Bookstore:  www.mc-store.com

Disclaimer:  Kevin and I worked together for several years - but I don't get paid in any way for selling his book.
