Rules for SAS Statements

There are only a few rules for writing SAS statements:

SAS statements end with a semicolon.
You can enter SAS statements in lowercase, uppercase, or a mixture of the two.
You can begin SAS statements in any column of a line and write several statements on the same
line.
You can begin a statement on one line and continue it on another line, but you cannot split a word
between two lines.

1.4 SAS data sets and data types

SAS reads data from anywhere (for example, raw data, and spreadsheets) and it stores the data in its
own special form called a SAS data set. SAS has only two types of variables: character and numeric.

1.5 The SAS Display Manager

You might use a general-purpose text editor on a mainframe to written a SAS program, submit it, and
send the output back to a terminal or to a file. On PCs, you might use the SAS Display Manager, where

you write your program in the Enhanced editor (Editor Window), see any error messages and comments
about your program and the data in the Log window, and view your output in the Output window. In
addition to the Enhanced Editor, an older program, simply called the Program Editor, is available for
Windows and UNIX users.
