Syntax: GA Procedure
To initialize your data and describe your model, you use programming statements with a syntax similar to the SAS DATA step, augmented with some special function calls to communicate with the genetic algorithm optimizer. Most of the programming statements used in the SAS DATA step can be used in the GA procedure, and these are described fully in the SAS Statements: Reference and Base SAS documentation. Following is an alphabetical list of the statements and special function calls used.
