Source Code Revision Control Systems and Auto-Documenting
Source Code Revision Control Systems and Auto-Documenting Headers for SAS® Programs on a UNIX or PC Multiuser Environment Terek Peterson, Alliance Consulting Group, Philadelphia, PA Max Cherny, Alliance Consulting Group, Philadelphia, PA ABSTRACT This paper discusses two free products available on UNIX and PC RCS, which is a more powerful utility than SCCS, was written in environments called SCCS (Source Code Control System) and early 1980s by Walter F. Tichy at Purdue University in Indiana. It RCS (Revision Control System). When used in a multi-user used many programs developed in the 1970s, learning from environment, these systems give programmers a tool to enforce mistakes of SCCS and can be seen as a logical improvement of change control, create versions of programs, document changes SCCS. Since RCS stores the latest version in full, it is much to programs, create backups during reporting efforts, and faster in retrieving the latest version. RCS is also faster than automatically update vital information directly within a SASâ SCCS in retrieving older versions and RCS has an easier program. These systems help to create an audit trail for interface for first time users. RCS commands are more intuitive programs as required by the FDA for a drug trial. than SCCS commands. In addition, there are less commands, the system is more consistent and it has a greater variety of options. Since RCS is a newer, more powerful source code INTRODUCTION control system, this paper will primarily focus on that system. The pharmaceutical industry is one of the most regulated industries in this country. Almost every step of a clinical trial is subject to very strict FDA regulations.
