RESTSCRN

 Function
  Restore the screen from the buffer previously saved with SAVESCRN.

 Syntax
  RESTSCRN   No arguments are required

 Remark
  PCBoard will save and restore the screen before and after certain
  functions, such as SysOp chat.  This allows the user to continue right
  where he left off without having to remember what was on the screen
  before being interrupted.  You can add that same functionality with
  SAVESCRN and RESTSCRN.  SAVESCRN allocates memory for a buffer in which
  to save the screen.  If SAVESCRN isn't followed by RESTSCRN then that
  memory will never be deallocated.  Finally, this statement will work
  regardless of ANSI availability; the screen is only saved up to the
  position of the cursor and this statement assumes that it can safely
  restore the screen using standard teletype conventions to just scroll
  the data onto the display.
