将choose选项添加到lisp
我有一个Lisp程序的Lisp程序，告诉我线的长度。但它只在厘米中显示。
我希望它会问我是用米还是厘米表示。
类似这样的选项可供选择
我希望你能帮我

;;-------------------------=={ Length Field }==-------------------------;;
;; ;;
;;This program allows a user to generate a field expression ;;
;;referencing the length/perimeter/circumference of one or more ;;
;;selected objects. In the case of selecting multiple objects, the ;;
;;field expression will reference the sum of the lengths of all ;;
;;objects in the selection. ;;
;; ;;
;;The user may opt to specify a point at which to create a new ;;
;;multiline text object housing the field expression, pick a table ;;
;;cell in which the field should be inserted, or select an existing ;;
;;single-line text, multiline text, multileader, or attribute to ;;
;;be populated with the field expression. ;;
;; ;;
;;Upon issuing the command syntax 'LF' (Length Field) at the AutoCAD;;
;;command-line, the program first prompts the user to make a ;;
;;selection of objects for which to return the length summation. ;;
;; ;;
;;At this prompt, the user may select any number of Arcs, Circles, ;;
;;Lines, 2D Polylines (light or heavy), or 3D Polylines. ;;
;; ;;
;;The user is then prompted to specify a point or table cell to ;;
;;insert a field expression referencing the summation of the lengths;;
;;of the selected objects. ;;
;; ;;
;;At this prompt, the user may also choose the 'Object' option in ;;
;;order to populate the content of an existing annotation object ;;
;;with the field expression. ;;
;; ;;
;;Upon choosing this option, the user may select any single-line ;;
;;text (DText), multiline text (MText), single-line or multiline ;;
;;attribute, attributed block, or multileader (MLeader) with either ;;
;;multiline text or attributed block content. ;;
;; ;;
;;If the user selects an attributed block or attributed multileader ;;
;;with more than one attribute, the user is presented with a dialog ;;
;;interface listing the available attributes, and is prompted to ;;
;;select a destination for the field expression. ;;
;; ;;
;;The user may optionally predefine the target block/multileader ;;
;;attribute by specifying the attribute tag where noted at the top ;;
;;of the program source code. ;;
;; ;;
;;The resulting field expression will display the sum of the lengths;;
;;of the selected objects, formatted using the field formatting code;;
;;specified at the top of the program. ;;

如果你看这一行（setq fmt“L*=%lu6%pr2 cm”），它保持格式，而不测试lu6长度单位6=“当前单位”，精度2小数需要更改单位或将长度除以100，即为米。因此，如果m或Cm，则将fmt设置为适合。如果执行多行文字选择字段，则拾取一个对象，您可以看到文字发生变化 如何做“如果”的事情
我是新手。
有人能给我指路吗？
有任何教程如何做这种“如果” 下载我原来的长度场程序。
更换线路63-65：
