My wild and random guess because that is a very broad question.
SAS currently has two ways to develop programs - EG (Enterprise Guide) which is mostly point and click - similar to SPSS.
SAS BASE or FOUNDATION involves coding from 'scratch' like R or even Fortran or C++. You can access SAS BASE/FOUNDATION and write code through EG
BASE/FOUNDATION is very powerful in allowing to create tables/graphs automatically that are required for clinical trials. I automated the reporting for the CONSORT diagrams required for a clinical trial recently.

Sometimes "from scratch" means that you write the program starting fresh. The opposite would be copying an existing program, and making a few changes to it to make it applicable to your current data.
