Here's a list of some of the functions available for use in SAS. For a complete list of functions which are available see the SAS online help under SAS SYSTEM HELP--SAS LANGUAGE--SAS FUNCTIONS--FUNCTION CATEGORIES or the SAS Language Reference.

Functions must appear as part of a SAS statement. Usually, this is as part of an assignment statement. Functions may be used as part of a logical test, e.g., in an if-then statement. Examples:

```
y=function(x);
function(x); /* not valid */
if function(x)>5 then ...;
```
