我想在表格中将2.16更改为2,16。这是我的代码
return我的代码正常运行，我已经调试，实现了行(defun write-segment (filename segment)
(cond ((null segment)
(with-open-file (out filename
:direction :output
:if-exists :append
:if-does-not-exist :create)
(format out "~%")))
(T (with-open-file (out filename
:direction :output
:if-exists :append
:if-does-not-exist :create)
(format out "~D " (first segment))
(write-segment filename (cdr segment))))))
。但在那之后，该表仍然显示2.16，而不是2,16。我不知道为什么？在更换字符串后，是否需要刷新表格或类似内容？
