The “COUNT” field reports the table position of the row retrieved or saved for those commands that change the COUNT field of the COMMAND-AREA. “COUNT” may also affect the next command executed if that command takes a count parameter, for example, the FC (Fetch by Count) or GN (Get Next row) commands. “COUNT” is therefore an unprotected field that users may set to control the operation of such commands.

In a multitasking or multi-user online environment, results for commands that utilize a count or sequential accessing of table rows may get unexpected results if another task/user is updating or deleting rows in the same table.
