Before we continue, there are two things about SAS programming you need to know:
1. SAS is insensitive to case
In other words, the following code returns the exact same result in SAS:
Data Test;
a = 1;
Run;OR
data test;
a = 1;
run;OR
daTa tESt;
A = 1;
RuN;2. SAS is insensitive to indentation
The two sets of code also return the exact same result in SAS:
Data Test;
a = 1;
Run;OR
Data Test;
a = 1;
Run;
