7–78 Digital Emulation
Partial Line Up (PLU) — Superscripting
ASCII Code ESC L
Hex Code 1B 4C
Dec Code 27 76
Purpose Print superscripted characters.
Discussion This sequence moves the active position up a distance equal to 1/2 a
vertical line increment, as determined by the currently active font. The
Partial Line Down (PLD) sequence returns the active position to the
previous baseline.
The printer prints superscripted characters that go over the top page margin
without disrupting the baseline of the superscripted characters. If PLU occurs
while the active position is over the top margin, it has no effect; however,
other active line affecting control functions still produce their distinctive
effect.
For example, if the active line is over the top margin, a carriage return <CR>
places the active line at the top of the margin and characters are imaged as
superscript until disabled. If the active line is below the bottom margin, a
carriage return <CR> performs a form feed and characters are imaged as
superscripts until disabled.
