SAVESCRN

 Function
  Save the current screen to a buffer for later restoration with RESTSCRN.

 Syntax
  SAVESCRN   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; this statement will only save the
  screen up to the position of the cursor.  It is assumed that the screen
  can be safely restored using standard teletype conventions to just scroll
  the data onto the display.
