Introduction to Dynamics and Macro Variables

If all of the variable names and options that are referenced in GTL templates had to be "hard coded" in the compiled template, it would require that you redefine and recompile the template every time you created the same type of graph with different variables. SAS programmers are familiar with using SAS macros and macro variables to build application code in which variables and other parameters can be specified by a calling program. The same techniques, as well as other techniques unique to ODS templates, can be applied in GTL to create reusable templates.
