一个改进的Comment函数
这个函数是我在论坛上看到的，这个函数主要作用是在图表上输出多行的Comment(注释)，觉得挺有用，所以和大家分享一下：

//Determines how many of your previous comments are shown
extern int MaxCommentsToShow=25;
//An array to hold all of the comments
string allcomments[];

//+------------------------------------------------------------------+
//|             Manage comments - Written by imt4       |
//|                         www.imt4.com                         |
//+------------------------------------------------------------------+
void managecomments(string addcomment)
{
string tempcomments[];
int commentscroll;
string output;
int CommentCount = ArrayRange(allcomments, 0);
if(CommentCount<MaxCommentsToShow)
   {
   ArrayResize(tempcomments,CommentCount+1);
   ArrayCopy(tempcomments,allcomments,1,0,WHOLE_ARRAY);
   }
else
   {
   ArrayResize(tempcomments,MaxCommentsToShow);
   ArrayCopy(tempcomments,allcomments,1,0,MaxCommentsToShow-1);
   }
tempcomments[0]=addcomment;
CommentCount = ArrayRange(tempcomments, 0);
ArrayResize(allcomments,CommentCount);
ArrayCopy(allcomments,tempcomments,0,0,CommentCount);

for(commentscroll=0;commentscroll<CommentCount;commentscroll++)
   {
   output = output + allcomments[commentscroll] +"\n";
   }
Comment(output);
}
