Purpose• Quick References is meant to be a resource to help
understand the database and data sources.• Some of this information may appear elsewhere
but not in the same format.• Some of the information included here is not
included elsewhere in the documentation, such as programming tips.
• Quick References begin with a hyperlinked table of contents.

Programming examples• Basic programming examples
Include basic programming code for common tasks such as opening a file, joining files, recoding variables, and running routine procedures.
• SPSS programming examples are in two sections. Menu driven and syntax.
• SAS is syntax only.• Both sections include a few programming tips
and a warning.

Programming examples• The examples in the slides are for guidance, but
they do not replace your installation software documentation, local programming standards, and procedures, and may not be using the same software version as installed at your site. SAS, SPSS, and other software have websites and
may have examples of programming code. Conferences such as the SAS Global Forum publish
presentations with examples of programming code. Web searches can provide programming examples to
use at your own risk.
