PLU top-level constant
String
const PLU
Partial Line Backward.
PLU causes the active presentation position to be moved in the presentation component to the corresponding position of an imaginary line with a partial offset in the direction opposite to that of the line progression. This offset should be sufficient either to image following characters as superscripts until the first following occurrence of PARTIAL LINE FORWARD (PLD) in the data stream, or, if preceding characters were imaged as subscripts, to restore imaging of following characters to the active line (the line that contains the active presentation position).
Any interactions between PLU and format effectors other than PLD are not defined by Standard.
Implementation
const String PLU = '${ESC}L';
