Question

%macro showpage1( index, show, url );
    %let url1 = &url;
    filename _next url "&url";

    data search_website;
        infile _next length = len lrecl = 32767;
        input text $varying32767. len;    
        if index(text, '<span>') or index(text, '</span>');
        retain i;    
        if index(text, '<h2 class="title"') then i+1;
    run;

    data counting;
        set search_website;
        by i;    
        if first.i then count = 0;
        count+1;
    run;

    proc transpose data=counting out=search_one_line prefix=info;
        by i;
        id count;
        var text;
    run;

    data info1_&i (keep=var1 var 2 var3);
        set dataset1;
    run;

    options missing=0;

%mend showpage1;

我希望代码获取输出，尝试计算尺寸权重（L x W x H / 5000），请一位有人帮助我吗？

输入长度，宽度，高度值后，我无法获得尺寸重量。

您使用的是IsNumber（），它不是本机函数。试试这段代码

<html>

			else
			{

		function validatecal(form)
