PPB-Rectangle-Offset

This field specifies how many characters not to update within the rectangle. The value you specify for PPB-Rectangle-Offset is the position within the specified rectangle (defined by PPB-Update-Width and PPB-Update-Height) at which you wish to start updating the panel. If you intend to update the entire rectangle, you should set the PPB-Rectangle-Offset field to 0.

You can choose to update an irregular-shaped area of a rectangle by specifying values for both the PPB-Update-Count and PPB-Rectangle-Offset fields.

If you want to update the unshaded part of the panel you have to use PPB-Update-Count and PPB-Rectangle-Offset to specify how many characters are to be updated, and where the updating is to start:

1. 406 characters of the panel are to be updated (6 characters on the fifth line and 20 full lines, each line being 20 characters wide) by moving 406 to PPB-Update-Count.
2. Updating starts on the fifth line of the rectangle, beginning with the fifteenth character, so you need to skip the first 94 characters of the rectangle (four lines of 20 characters each, plus 14 characters of the fifth line). Start updating by moving 94 to PPB-Rectangle-Offset.
