Units can be specified, as with length, or the default will apply. Goptions is used to set various defaults for the session. For example, if you want to specify your graph sizes using inches, say gunit=in (other choices are cm for centimeters, or pct for percent of display area, or cell for character cell units).

User-defined formats allow you to attach labels to the values for a variable so that the output from SAS procedures is more readable. For example, if sex is a numeric variable coded as 1 for males and 2 for females, the user-defined format can be set up so that the values "male" and "female" are printed in SAS output, rather than 1 and 2.

Variable names: Variable names may be one through eight characters in length. All variable names must begin with an alphabetic character (A-Z, a-z) or an underscore (_). Subsequent characters may include digits. A variable list such as Vl-V5 means V1, V2, V3, V4, and V5. SAS matches variable names precisely character-wise, but not case-wise.
