We use the in-built SAS data set called CARS available in the SASHELP library. These variables can be accessed by SAS programs in which they are declared as part of the program. They are typically used to supply different variables to the same SAS statements sl that they can process different observations of a data set. The local variables are declared with below syntax. Here the Value field can take any numeric, text or date value as required by the program. The Macro variable name is any valid SAS variable. The variables are used by the SAS statements using the & character appended at the beginning of the variable name. Below program gets us all the observation of the make 'Audi' and type 'Sports'. In case we want the result of different make, we need to change the value of the variable make_name without changing any other part of the program. Where make = &make_name and type = &type_name In case of bring programs this variable can be referred again and again in any SAS statements.

#How to download sas university edition in mac code
When the above code is run we get the same output as the previous program. But let’s change the type name to 'Wagon' and run the same program. Macro is a group of SAS statements that is referred by a name and to use it in program anywhere, using that name. It starts with a %MACRO statement and ends with %MEND statement. Where make = "&make_" and type = "&type_" The below program decalres a group of SAT staemnets under a macro named 'show_result' This Macro is being called by other SAS statements. SAS has many MACRO statements which are in-built in the SAS programming language. They are used by other SAS programs without explicitly declaring them.Common examples are - terminating a program when some condition is met or capturing the runtime value of a variable in the program log. This macro statement writes text or macro variable information to the SAS log. In the below example the value of the variable 'today' is written to the program log. Macro %RETURNĮxecution of this macro causes normal termination of the currently executing macro when certain condition evaluates to be true. In the below examplewhen the value of the variable "val" becomes 10, the macro terminates else it contnues. When the above code is run we get the following output. GETTING REPORT IN SAS UNIVERSITY EDITION CODE This macro definition contains a %DO %WHILE loop that ends, as required, with a %END statement. In the below example the macro named test takes a user input and runs the DO loop using this input value.
