Preprocess and Postprocess Code

In some cases, you might want to assign SAS options, load format catalogs, use LIBNAME statements, or run macros before running a data query. You can unlock the code to enter the statements, but that prevents you from using the Design tab. However, the Preprocess view or Postprocess view might enable you to supplement the data query while using the code generation features of the Design tab.
Any SAS statements that you enter in the Preprocess view or Postprocess view are included in the All Code view.
