PUTOVR

- Additional information
- PUTOVR is a record-level keyword used with OVRATR or OVRDTA to
permit the override of either display attributes or data contents
(or both) of specific fields. By using PUTOVR, you can reduce the
amount of data sent to the 5250 display device. In WebFacing, all
fields are sent to the Web browser whenever a page is displayed,
and WebFacing does not support the partial update of a Web page.
As a result, there is no performance gain by using PUTOVR in WebFacing.
The keyword is not supported by WebFacing and will be ignored, so
your application may not work the same as 5250. For example, on 5250
the output operation of a record that has PUTOVR
specified will only update the PUTOVR record (that
is, update the fields that have OVRATR or OVRDTA
specified). Any existing records on the display will remain
untouched. However, when the same output operation is executed in
WebFacing, any existing records on the display will be removed if
OVERLAY is not specified on the PUTOVR record. To avoid existing
records being removed from the display, you can add the OVERLAY keyword
on the record which has PUTOVR specified.
