Hi,

Please note that RSUSDEDLT(*YES) assumed that you have NO programs that
read the file sequentially, assuming that record n was added before record
n+1!

Hi Scotty,

Beware reoragising files on some legacy applications. Some of them use
releative record numbers to access data and will crash if the file is
reorganised outwith their control software. Check with your application
provider

If it is safe to reorganise the file and the file is likely to
frequently have large numbers deleted records, you could try changing
the file to reuse the space occupied by the deleted records. Use -

CHGPFM fileName REUSEDLT(*YES).

The is a very slight performance hit on doing this, but it eliminates
the need to regularly reoganise files, and all the hasle associated with
it.
