The "All Programs" links each cause to be downloaded a tar file about 700Mbytes in length. The files associated with each of the five computer programs, BOSOR4, BIGBOSOR4, BOSOR5, PANDA2, and GENOPT, include the program source files, the program executable files, sample cases, documentation, and certain utility files, including a plotting application called plotps, written by Bill Bushnell. BIGBOSOR4 supersedes BOSOR4 because BIGBOSOR4 handles shells with many more shell segments than BOSOR4, and BIGBOSOR4 will analyze prismatic shells as well as shells of revolution. BOSOR4 is still needed, however, because BOSOR4 routines are used by PANDA2. BOSOR5 (elastic-plastic buckling) does not supersede BIGBOSOR4 (elastic buckling) because BOSOR5 does not do as many different types of analysis as does BIGBOSOR4, nor does BOSOR5 handle prismatic shells, as does BIGBOSOR4. BIGBOSOR4 handles shells with many, many more segments than does BOSOR5.
