User-written code (1) Traditional model: all SAS® code is directly user-written or indirectly written: generated by user-written SAS macros, Lua code, DATA steps. SAS macros can now operate on arbitrary text, via PROC STREAM.

User-written code (2) Batch environment process shown; windowing, interactive line mode environments are similar:

System-generated SAS code Many SAS tools can generate SAS code, e.g.: SAS Enterprise Guide SAS Studio (SQL GUI) SAS Data Integration Studio and many more! Diverse: operational use of generated SAS code can vary by tool & application; also importance of underlying processes may vary with context.

Client-server environment Most system-generated code is produced by SAS tools that run in the client-server environment. Such code can be run in client-server environment OR -with changes - in other environments
