LOCK()

Class

Manual Locking

Purpose

Function to lock record

Syntax

LOCK([<workarea | alias>])

See Also

FLOCK(), LOCKF, LOCKR, RLOCK(), UNLOCK

Description

The LOCK() function attempts to lock the current record. If successful, it returns .T. and the record is locked. If the record is already locked by another user then it returns .F..

Note: Recital automatically performs file and record locking so, in most situations, this function is unnecessary. It is included for compatibility with programs written with other products. If the optional <workarea | alias> is specified, then the function will operate in that <workarea | alias>.

Example

do while not lock()
    set message to "Record is in use."
    sleep 2
enddo
