; 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:
;
; 07/25/2002: Added wildcard block name selection filtering
;
; 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
; )
