LJ SERIES 2D EMULATION
Absolute move: If the # value has no sign, the cursor is moved
down # rows from the top margin.
Relative move, positive: If the # value is preceded by a plus (+)
sign, the cursor is moved # rows down from the current cursor
position.
Relative move, negative: If the # value is preceded by a minus
(-) sign, the cursor is moved # rows up from the current cursor
position.
If an absolute # value (i.e., with no sign) or negative # value
exceeds the top or bottom edges of the printable area, the
cursor is moved to the appropriate edge of the printable area. If
a positive # value specifies a position beyond the bottom of the
printable area, the cursor is moved off the page. The Vertical
Cursor Position commands ignore the perforation region.
Example To move the cursor from line 25 to line 2, enter:
E &a2R
Hex 1B 26 61 32 52
Dec 27 38 97 50 82
or, as a relative move,
E &a-23R
Hex 1B 26 61 2D 32 33 52
Dec 27 38 97 45 50 51 82
Vertical Cursor Position (Decipoints)
Purpose The Vertical Cursor Position (Decipoints) defines the absolute or
relative position of the vertical cursor in units of decipoints
(1/720th of an inch). The height of a row is defined by the
current Vertical Motion Index (VMI) setting.
Syntax
E &a#V
Hex 1B 2A 61 # 56
Dec 27 42 97 # 86
where # represents the number of decipoints to move or the
absolute position to move to. The # is valid up to two places to
the right of the decimal point.
