Search the archives for SQL IDENTITY and you'll probably come up with
a bunch of useful examples.  http://archive.midrange.com There are
several native RPG ways to go about this.

1) Use a data area to store the last number used
*lock in lastno
      add 1      lastno
     out lastno

2) Get the highest key by looking at the last record
*hival setll
       readp
       add 1 key
...

3) Store the last number used in another database file

Hope this gets you started.
