line starve

line starve  [MIT] 1. vi. To feed paper through a printer
   the wrong way by one line (most printers can't do this).  On a
   display terminal, to move the cursor up to the previous line of the
   screen.  "To print `X squared', you just output `X', line starve,
   `2', line feed."  (The line starve causes the `2' to appear on the
   line above the `X', and the line feed gets back to the original
   line.)  2. n. A character (or character sequence) that causes a
   terminal to perform this action.  ASCII 0011010, also called SUB or
   control-Z, was one common line-starve character in the days before
   microcomputers and the X3.64 terminal standard.  Unlike `line
   feed', `line starve' is *not* standard {{ASCII}}
   terminology.  Even among hackers it is considered a bit silly.
   3. [proposed] A sequence such as \c (used in System V echo, as well
   as {{nroff}} and {{troff}}) that suppresses a {newline} or
   other character(s) that would normally be emitted.
