crsid1-crsid3 are assigned values of the data set variable Course_code from each of the first three rows,他们分别对应数据集的前三行的观测的值 如果规定的group数大于实际的数量,那么按照实际多少个来创建宏 createone macro variablethat willhold all values ofa certain data setvariable. procsql nopr...
SAS macro facility has been a very important tool in SAS programming for many years. The CALL SYMPUT routine and DATA _NULL_ are the traditional methods to create macro variables from SAS data. However, PROC SQL is much more powerful andefficient in creating macro variables thanks to the in...
%create_macro_variable(my_variable, "Hello, World!"); 使用宏变量:在程序的其他部分使用宏变量时,可以使用&符号引用它们的值。例如,下面的代码使用了上述创建的宏变量: 代码语言:txt 复制 data mydata; set mydataset; new_variable = "&my_variable"; run; 在上述代码中,宏变量"my_variable"的值被赋给...
1).Automatic Macro Variables:可以理解为系统宏变量或者自动宏变量 例如sysdate 2).user-defined macro variables 3.按作用域分为两类: Automatic Macro Variables都是全局宏,在macro外定义的也是global micro variable,在macro内定义的是本地宏变量的。(宏变量的作用域不涉及文件(%include问题),数据集或者proc步。...

if _n_=1 then call execute('proc format; value vs1t'); call execute(cats(AVISITN)||' = '||quote(cats(AVISIT))); if eof then call execute('; run;'); run; 通过宏变量创建。 /*方法2: macro variable*/ proc sql noprint;
我想循环使用逗号分隔的宏变量,如下所示,我也在proc sql语句的where条件中使用该变量: %let example = (1, 2, 3, 4) 我发现以下语法几乎涵盖了我的情况: %macro px; %let value = 1 2 3 4; %local i next_value; %let i=1; %do %while (%scan(&value, &i) ne ); ...

自动生成宏变量有两种方法,data步里用call symputx(),或者proc sql中用select into:。 零售项目中,万同学的代码里有很多select into:的使用;唐同学的宏里面就有不少call symput()。 call symputx的用法举例: /*6.1b using symputx to create a macro variable*/ /*生成宏变量jane_age,取值为Data步生成的数据...
/*方法2: macro variable*/ proc sql noprint; select catx(' = ', cats(AVISITN), quote(cats(AVISIT))) into :fmtlst separated by ' ' from demo order by AVISITN; quit; proc format; value vs2t &fmtlst; run; 通过CNTLIN=选项创建。
