Read only state

Read only state {( aTable )} -> Function result

Parameter	Type		Description
aTable	Table	→	Table for which to test read-only state, or Default table, if omitted
Function result	Boolean	←	Access to table is read-only (TRUE), or Access to table is read-write (FALSE)

Description

This function tests whether or not the state of aTable is read-only for the process in which it is called. Read only state returns TRUE if the state of aTable is read-only. Read only state returns FALSE if the state of aTable is read/ write.

Example

The following example tests the state of an [Invoice] table. If the state of the [Invoice] table is read-only, it is set to read/write, and then the current record is reloaded.

 If(Read only state([Invoice]))
    READ WRITE([Invoice])
    LOAD RECORD([Invoice])
 End if

Note: The invoice record is reloaded to allow the user to modify it. A record that was previously loaded in a read-only state will remain locked until it is reloaded in a read/write state.
