sas Getting started with sas Hello World!
Example
Due to the stucture of SAS, there are three main ways to create "Hello World!" examples:
- Within a data step to put a message into the SAS log (
_null_denotes that no output dataset should be created):
data _null_;
put "Hell" "o World!";
run;
- Within a data step to store "Hello World!" within a variable (
foodenotes that an output dataset calledfooshould be created that a) contains only one record and b) contains only one variable:bar, which has a value ofHello World!):
data foo ;
bar="Hello" ;
put bar= "World!";
run ;
- Via the SAS Macro language (in 'open code' outside of any data steps).
&identifies a call to a macro variable and.identifies the end of the variable (if a white space character is not wanted):
%let foo=Hello;
%put &foo.o World!;
- Hybrid: Using a macro variable within a data step:
%let foo=Hello;
data _null_ ;
put "&foo World!";
run ;
