Add a forward slash and an asterisk at the beginning of the comment, and place an asterisk and a forward slash at the end of the line.Īn example SAS program containing comments might look like this: * Check the variables in the most recently used dataset using the CONTENTS procedure.

All text between the asterisk and the semicolon will be commented out.

Add an asterisk at the beginning of the line, and add a semicolon at the end of the text being commented out.

There are two ways to "comment out" a line of text or code in a SAS program: A well-commented program helps you to remember what your thought process was when you first created the program, and helps other users decipher what your program is doing. Comments make a written program more understandable by documenting what the program is doing (or should be doing), and why. Here is an example of how a typical program would be set up, making use of indentations and spacing, one statement per line, and capital letters.Ī comment is a line or block of text that SAS ignores during the execution of a program.

Most SAS programmers use capital letters, indentations, and spacing in a way that makes it easier for themselves and other users to read and understand their program.

A statement can span more than one line, as long as it ends with a semicolon.

Multiple statements on the same line are okay, provided they are separated by a semicolon.

Extra lines between statements are ignored.

Indentations or spacing before a statement are ignored.

SAS is not case sensitive uppercase and lowercase letters are recognized as the same, even for variable names.

SAS is more relaxed than other coding languages when it comes to capitalization, indentation, and line breaks. The example text string below shows that SAS recognizes the first two lines as text (indicated by the coloring), but only recognizes part of the text as such in the third line. One word of caution: if your text contains an apostrophe, then you must enclose it with quotation marks.

You know you have properly typed text values when SAS changes the color of the words into a purplish-pink color. You will need to enclose text in quotation marks or apostrophes if you need to reference values of a character variable, reference a file directory, or assign a title to your output, to name a few example. It doesn’t matter which one you choose, but be sure each text block starts and ends with the same one. SAS recognizes text as long as it is enclosed in quotation marks ( "text") or apostrophes ( 'text').

Omitting the semicolon is the most common mistake new users make. This generally corresponds to every line ending in a semi-colon, but sometimes your commands or statements will be more than one line and a semicolon is only necessary at the end of the statement. SemicolonsĮvery statement must end with a semicolon.

There are some conventions of SAS syntax that new users should know before getting started. SAS syntax is the set of rules that dictate how your program must be written in order for SAS to understand it. You can save your program so that it can be edited and reused after it’s written.

A SAS program is written in the Editor window and contains a series of statements that tell SAS what to do (e.g., import a dataset, give a frequency count of a variable).
