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.
