READ ONLY {(aTable | *)}

ParameterTypeDescription
aTable | *TableTable for which to set read-only state, or
* for all the tables, or
Default table, if omitted

Description

READ ONLY changes the state of aTable to read-only for the process in which it is called. All subsequent records that are loaded are locked, and you cannot make any changes made to them. If the optional * parameter is specified, all tables are changed to read-only state.

Use READ ONLY when you do not need to modify the record or records.

Note: This command is not retroactive. A record is loaded according to the table's read/write status at the time of loading. To load a record from a read/write table in read-only mode, you must first change the table state to read-only.
