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 with PUTOVR in effect will only update
the PUTOVR record (i.e., update the fields with OVRATR or OVRDTA in effect).
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.
