## RETRY Usage

The `RETRY` statement is used within an `ON ERROR` statement block (see `ON ERROR` statement). It is used to reattempt to obtain a record which is in hold status for another user.

When a record to be held is already in hold status for another user, Natural issues Error Message 3145. See also the session parameter `WH` (Wait for Record in Hold Status).

The `RETRY` statement must be placed in the object that causes the Error 3145.

For details on record hold logic, see the section Record Hold Logic in the Programming Guide.

## RETRY Restrictions

This statement can only be used to access Adabas databases.
