We discuss the application of SAS to a number of environmental datasets. Usually reports, graphical visualizations, summary statistics, and subset or aggregate datasets must be generated from one or more of these datasets. A library of SAS macros was developed while building a reporting system for several large and complex environmental datasets. This paper discusses a number of SAS code segments from these macros that may be easily extended to other similar projects. The intended audience is the SAS macro programmer and concentrates on several key areas: · Using the DATASTEP to generate CSV and XML file output corresponding to data used by GPLOT and GCHART; · Augmenting basic GOPTIONS and CHART options to produce graphical output (JPEG) for several different variables in time-series datasets; · Using local macro variables to generate dynamic AXIS statements (for graphics) and WHERE statements (for DATASTEP). The SAS code is contained within macro definitions and offers maximum opportunity for code reuse
