ABORT() (BOOLEAN)

 Function
  Returns a flag indicating whether or not the user has aborted the
  display of information.

 Syntax
  ABORT()   No arguments are required

 Return Type & Value
  BOOLEAN
  If the user has aborted the display of information by answering no
  to a MORE? prompt or by hitting K or X display, this function
  returns TRUE.  Otherwise FALSE is returned.

 Remarks
  Unless specifically disabled, the user can abort any display at any
  time by hitting K or X or by answering no to a MORE? prompt.  If the
  user does this, PCBoard will not display any further information until
  the display is reset via the RESETDISP statement.

  This function should be checked occasionally during long displays of
  information to determine if the user wants to abort.  If the function
  returns TRUE, you should stop printing information and continue with the
  next part of the program after using RESETDISP.

 Examples
  INTEGER I
  STARTDISP FCL
  ' While the user has not aborted, continue
  WHILE (!ABORT()) DO
    PRINTLN "I is equal to ",I
    INC I
  ENDWHILE
  RESETDISP
