看到高飞鸟的帖子，有一不懂之处
(defun c:API (/ oEx oBk Mod str a)
  (setq oEx (vlax-create-object "excel.application"))
  (setq obk (vlax-invoke (vlax-get oEx 'workbooks) 'add))
  (setq mod (vlax-invoke (vlax-get (vlax-get obk 'VBProject) 'VBComponents) 'add 1))
  (setq str "Sub MyMacro()\np = 12 + 23\nEnd Sub")
  (vlax-invoke (vlax-get mod 'CodeModule) 'AddFromString str)
  (vlax-invoke oEx 'run "MyMacro")
  (vlax-put oEx 'DisplayAlerts 0)
  (vlax-invoke obk 'close)
  (vlax-invoke oEx 'quit)
  (vlax-release-object mod)
  (vlax-release-object obk)
  (vlax-release-object oEx)
  (print a);a放到何处才能看到p;(setq a (加到何处))
  (princ)

通篇都没有A这个变量，怎么能显示？
