TRANSACTION Property

10.5, PLBCMP GUI Only

The TRANSACTION property enables or disables transactions. The property uses the following format:

TRANSACTION={value}

Note the following:

1. TRANSACTION may be used in CREATE, GETPROP, or SETPROP statements of a DATATABLE.

2.  When transactions are enabled, the DATATABLE tracks all operations using an undo stack. This allows the PL/B program to execute the 'Commit', 'Rollback', and 'Undo' methods for the DATATABLE.

3. {value} is a decimal number, a Numeric Variable, an Expression, or a keyword as defined in PLBEQU.INC. The supported values and keywords are:

 

Value	Keyword	Transactions are ...
0	$OFF	disabled (default).
1	$ON	enabled.

 

4. The UNDO stack only contains the last one hundred (100) actions since the last COMMIT or ROLLBACK.
