The results associated with using macro options are automatically displayed on the SAS Log. The SAS System offers users a number of useful system options to help debug macro issues and problems. What System Options Would You Use To Help Debug A Macro? While, PROC CONTENTS display information about an SAS dataset. To display the contents of the SAS dataset, PROC print is used and also to assure that the data were read into SAS correctly. Explain What Does Proc Print, And Proc Contents Are Used For? Macros in SAS make a small change in the program and have SAS echo that change thought that program.
Parameters passed to the macro program customize the results without having to change the code within the macro program. A macro program can be reused many times. We can accomplish repetitive tasks quickly and efficiently. If we want use a program step for executing to execute the same Proc step on multiple data sets. For What Purposes Have You Used Sas Macros? The data types in SAS are Numeric and Character. Mention What Are The Data Types Does Sas Contain? There should be at least one space between each word or statementįor example: Infile ‘H: StatHWyourfilename.dat’ There should be a semi-colon at the end of every lineĪ data statement that defines your data set To run program successfully, and you have following basic elements: SYMPUT puts the value from a dataset into a macro variable where as SYMGET gets the value from the macro variable to the dataset. The informat will tell SAS on how to read data into SAS variables. SAS INFORMATS are used to read, or input data from external files known as Flat Files ASCII files, text files or sequential files). %macro plot (yvar= ,xvar= ) proc plot plot &yvar*&xvar run %mend plot %plot(age,sex) Macro parameters allow you to pass information into a macro. How Are Parameters Passed To A Macro?Ī macro variable defined in parentheses in a %MACRO statement is a macro parameter. PROC gplot has more options and can create more colorful and fancier graphics. What Are Automatic Variables For Macro?Įvery time we invoke SAS, the macro processor automatically creates certain macro var. The difference between the NODUP and NODUPKEY is that, NODUP compares all the variables in our dataset while NODUPKEY compares just the BY variables. Mention What Is The Difference Between Nodupkey And Nodup Options?
Proc glm performs simple and multiple regression, analysis of variance (ANOVAL), analysis of covariance, multivariate analysis of variance and repeated measure analysis of variance.
