这是你自己写的还是抄书上的?

data=temp;

=可能是空格

title2"&pr &year1时序图"；

全角分号大概是半角分号; macro variable的引用后面是不是少了个点, "&year1.时序图"

%mend plot;
run;

类似的run语句可以不写吧

3# PharmD 按照你们的提示修改后还是 %analyze(yes,Idx000001,1999,收盘价,clpr,1999);
这个地方出错，我是刚刚开始学习宏，对错误的原因不太明白，请多多指导，谢谢！

各位大虾们，下面是我运行朱世武教授书上的程序如下：
%macro create;
data=temp;
set Resdat.&dat end=final;
if year(date)=&year then do;
n+1;
output;
end;
if final then call symput("number",n);
/*创建的宏变量为number，其值为n*/
run;

%mend create;
%macro plot;
proc gplot data=temp;
title2"&pr &year1时序图"；
plot &price*date=1;
symbol1 v=star i=join r=1 c=red;
%mend plot;
run;

%macro analyze(getdata,dat,year,pr,price,year1);
%if %upcase(&getdata)=yes %then %create;
footnote "plot of &number of observations";
%plot;
%mend analyze;
run;

%analyze(yes,Idx000001,1999,收盘价,clpr,1999);
%analyze(yes,Idx000002,1999,收盘价,clpr,1999);
%analyze(yes,Idx000001,1999,收盘价,clpr,2000);
%analyze(yes,Idx000002,1999,收盘价,clpr,2000);
run;


在前面编译都非常正常，但是运行到宏analyse时出错，log上面显示错误如下：

globalize 'number'
for exmpale in %create:
%global number;

%macro create;
data temp;
set Resdat.&dat end=final;

xiezuosheng 发表于 2010-10-9 07:41

%macro create;
data temp;
set Resdat.&dat end=final;

13# PharmD 我也认为问题的症结在这里，我的本意是要定义一个temp数据集，这个数据集就是复制逻辑库Resdat中某个数据集的内容！如果不在宏里面运行，肯定是没问题的，
%macro create;
data temp;
set Resdat.&dat end=final;
