您好！感谢您阅读我的帖子，无论您是否恢复！我将恭候！
问题如下：
1，如何在bc环境下，启用鼠标的点击功能（可以用鼠标点击菜单项或指定光标位置）；
2，在bc环境下，调试过程中计算变量值出错。 是这样的：调试时Debug/Evaluate 的Evaluate段输入了整型变量 i 回车后在Result段 出现了Undefined Symbol i ？？？ 我已经定义了变量 i : int i;
i=strlen("abcde");

请求各位仁兄帮助！

why used BC?

变量没有赋初值？还是什么的...

最好把你写的程序原样贴出来
这样我们才好给你合理的解释

哈哈 ，谢谢各位的回贴。bc 是我在嵌入式编程所需的，由于本人也是初次接触，有相当多的问题不懂！虚心请教，还望仁兄多多指教。

程序段如下：
