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.
