Positioning of Displayed Text

Boundary left and right cursor positioning keys are made both line and first and last character dependent for more efficient screen utilization and increased throughput.

Horizontal scrolling of displayable text by segments to handle wide measures is well known. A degree of continuity is maintained by over lapping the segments a certain extent. Total continuity could be provided with wider screens, but costs cannot be justified in most instances. When horizontal cursor jump operations are considered, either page edges or margins are usually taken as the extreme boundaries. That is, it is common upon a left cursor jump from any segment to display the first segment with the left margin at the left screen edge and with the cursor on the first character position of one of the displayed lines. This can not only fail to lend itself to efficient screen utilization, but can hamper throughput. Consider the following. In the majority of cases, an operator's interest is on the cursored line and not the page as a whole. System positioning of a cursor at the left margin upon a line return operation can require an operator to manually reposition the cursor if the line is indented. This is because the first character on the line is usually the earliest point any editing is considered. As such, the operator must cursor through the indentation to arrive at the first character.

Also, the blank screen indentation reduces available screen for maintaining...
