; ----- COM-AND BBS file maintenance script (BULLETIN file)
; Commenced: 11/90 R.McG
; -----------------------------------------------------------------------
; Purpose:
; The script, named BBMAINT3.CMD, produces the main window for
; Bulletin functions of BBMAINT, and implements its functions. It
; is not directly callable itself.
; -----------------------------------------------------------------------
; Usage:
; N99 -> Text attribute value (Setup by BBMAINT.CMD)
; N98 -> BBMAINT Mainline cursor position
; N97 -> BBMAINT Mainline cursor position
; N96 -> our mainline cursor position
; N95 -> our mainline cursor position
; -----------------------------------------------------------------------
;
; This script is intended ONLY to be used for FCALL
;
IF NOT FCALLED
