Abstract

In order to solve several problems pertaining to the movement and use of the arrow keys in and around panel constructs and to improve user efficiency, the work station controller (WSC) will support programmable work station (PWS) cursor movement. PWS cursor movement means that the arrow keys cause the cursor to move to the next input position in the direction of the arrow. PWS cursor movement precludes the movement of the cursor to output-only areas of the panel. In order to enable cursor-sensitive help for panel text items when PWS cursor movement is active, the WSC will allow the user to cursor to text items that have associated help text.

Cursorable Text Items With Programmable Work Station Cursor Movement

       In order to solve several problems pertaining to the
movement and use of the arrow keys in and around panel constructs and
to improve user efficiency, the work station controller (WSC) will
support programmable work station (PWS) cursor movement.  PWS cursor
movement means that the arrow keys cause the cursor to move to the
next input position in the direction of the arrow.  PWS cursor
movement precludes the movement of the cursor to output-only areas of
the panel.  In order to enable cursor-sensitive help for panel text
items when PWS cursor movement is active, the WSC will allow the user
to cursor to text items that have associated help text.

      Fig. 1 illustrates the flow of display panel data between an
application program and a non-programmable terminal (NPT) in the
AS/400* system.  The host display data manager builds a physical data
stream representation of a display panel and passes it to the WSC for
presentation. The WSC controls the physical attachment of multiple
NPT devices.  Each NPT consists of a keyboard and display monitor and
has limited processing capability.

      In order to solve several problems pertaining to the movement
and use of the arrow keys in and around panel constructs and to
improve NPT user efficiency, the WSC will support programmable work
station (PWS) cursor movement. PWS cursor movement means that the
arrow keys cause the cursor to move to the next input position in the
direction of the arrow.  Thus, the cursor is always positioned in an
input-capable position within the panel.

      Many existing AS/400 applications associate help text with
rectangular areas of the panel.  The user can move the text cursor
into the rectangular area and press the Help key to request
information about that particular panel area. The application
determines what information has been requested based on the current
cursor location.  This is called cursor-sensitive help.

      PWS cursor movement precludes the movement of the cursor to an
output-only area of the panel.  This means that the user cannot move
the cursor to a panel text item (e.g., field prompt, output
information) and press the Help key to request more information
pertaining to that panel item.

entry and selection fields.  The selection cursor (reverse image bar
