Active Column and Active Line (Cursor Motion)

Active Column and Active Line (Cursor Motion)
This section describes cursor positioning command sequences. Line printers
do not have a cursor like the blinking place-marker on most computer
screens. The cursor position on a line printer is the space where the next
character will print. In this manual, cursor refers to the currently active print
position. Its location is the intersection of the active column and active line.
Horizontal and vertical positioning command sequences allow you to move
the active position anywhere on the logical page.
You can also specify either absolute or relative motion. Absolute motion
specifies the distance to move from a specific point on the logical page.
Relative motion specifies the distance to move from the currently active print
position.
The Partial Line Up (PLU) and Partial Line Down (PLD) command sequences
set half line increments for superscripting and subscripting.
