Re: create macro variable from data field Posted 09-05-2024 11:35 PM (6003 views) | In reply to dwaldo There is a data step way: data _null_; set have end=end_of_have; length value $10 freq 8; if _n_=1 then do
***Temp macro; %macro check_empty_var; %if &nvar. = 0 %then %do; data result; length Dataset $50 empvar $2000; dataset = "CLASS"; empvar = "There is no variable in the dataset Class!"; run; %end; %else %if &nvar. > 0 %then %do; %if &nvar. = 1 %then %do; pro...

宏程序 %make_empty_dataset.sas 的工作流程为: 首先读取Excel文件 ”SDTM_METADATA.xlsx“ 生成了数据集 _temp。 以varnum将读取到的所有观测排序。 在_temp的基础上生成数据集NULL_,(1)将读取到的观测总数记录到变量vars。(2)将原先Excel中的变量VARIABLE转换为 SAS变量var,并去除空格。(3)将Excel文件中的变...
7.If population is a macro variable obtained in the prior programs, take highly notice this variable is a character value. So if you use it in next calculation, try to avoid the statements like this: IF COUNT=&TRTA THEN PCT=’100’. As the var...
The macro also has dynamic features.The macro automatically provides the column totals, the number of missing values, and assigns SAS formats to the column variable based on the dataset. The macro will also automatically pull in the correct p-value for t-testsdepending on whether or not the ...
Show the SAS code that you want the macro to create. Explain what part of it needs to change. If it is just the dataset name and the variable name then converting it to a macro is trivial. So if the code looks like: data want ; set have; ... varname ... run; Then the macr...
