; -----------------------------------------------------------------
;
; Adds the COUNT command to AutoCAD, which counts, itemizes, and displays
; in tabular form, the number of insertions of each block in the selected
; objects, or the entire drawing.
;
; Add to ACAD.LSP, or load with (load"count")
;
; First implemented in May of 1990.
;
; Revision history:
;
; 10/13/1991:  General revisions for R11:
;
;              1.  Now ignores anonymous blocks and Xrefs.
;
;              2.  Added console/screen paging, pauses listing
;                  at each screen-full and waits for a keypress.
;
;    Notes on console paging:
;
;      1.  To disable console paging, add the following to COUNT.LSP:
;
;              (setq *cpage-disable* t)
;
;      2.  The number of physical console lines defaults to 25.  This
;          can be overridden by adding the following to COUNT.LSP
;
;              (setq *console-lines* <num> )
;
;          Where <num> is the integer number of physical screen lines.
;
;      3.  The screen-clear function defaults to (textpage) under R11,
;          and (textscr) under R10 (no screen-clearing is performed),
;          but it can be redefined by assigning a function that is to
;          be called to do a screen-clear to the symbol *clear-screen*.
;
;          The following example can be used with R10 if ANSI.SYS or
;          any compatible console-driver is installed, to clear the
;          display on each screen-page:
;
;               (defun *clear-screen* ()
;                  (textscr)
;                  (princ "/e[2J")
;                  nil
;               )
