When R:BASE is running in multi-user mode, the user has the added capability of forcing R:BASE to use row-level locking on some R:BASE commands. By default, the SET ROWLOCKS command is set on. You can set ROWLOCKS by choosing Utilities: Settings... then click the Multi-User button, or using the SET ROWLOCKS command at the R> prompt. Setting ROWLOCKS off is not recommended if all users intend to update the same tables.

R:BASE always uses row-level locking for the EDIT, EDIT USING, and ENTER commands.
