lock

Type

Processing Command

Purpose

The lock command is functional only when using DataEase on a LAN (local area network). The lock command prevents users from viewing, modifying, adding, or deleting data in forms and records being used by a report/procedure.

The lock command overrides the default multi-user locking rules assigned by the database administrator. To override the default locking rules, the first statement of the script must be either lock all files or unlock all files. If neither of these commands appears at the start of the script, the default locking rules govern LAN functioning until a lock or unlock command appears in the script.

All lock and unlock commands are automatically terminated at the end of a script.

Syntax
