那个高手有时间帮我完善一下一个类似 messagebox 的函数的？？
*调用dfmsg(msg,cr,msgt,msgc,col1,col2,col3,col4)
* msg 需要显示的内容
* cr 命令按钮控制
* msgt 标题栏显示的内容
* msgc check显示的内容，如果为空则不显示
* col1 界面背景色
* col2 文字颜色
* col3 命令背景色
* col4 命令文字色
*其中f_color_01,f_color_02是我程序的全局变量，用于控制表单的颜色！
PROCEDURE dfmsg
LPARAMETERS msg,cr,msgt,msgc,col1,col2,col3,col4
LOCAL ARRAY tmp_1(1)
LOCAL tmp_2,tmp_3,tmp_4
PUBLIC tmp_5
* 检查函数的输入数据，并定义默认值
