attr indication

From The x3270 Wiki

An attr indication is an XML-specific b3270 protocol element that describes changed screen attributes over a region, with the text remaining the same. It is always nested inside of a row indication. If a particular screen attribute is not specified by this indication, then it stays the same.

Attribute Always present? Purpose
column yes Column number, with 1 at the left
count yes Number of affected columns
fg no Foreground color
bg no Background color
gr no Graphic rendition


See the screen indication for an example.
