Bernese GPS Software Version 5.0 - Bernese GNSS Software

21. Program Structure
21.1 Introduction
In this chapter we give an overview of the programs of the Bernese GPS Software Version
5.0 . This includes the program structure and a complete list of all Bernese programs.
We also include the programs which are not supported by the menu system.
Furthermore, we add remarks concerning programming standards and programming conventions
for those users who, for whatever reason, would like to (or have to) change the
source code.
21.2 Overview of the Directory Structure
The directory structure of the program environment is shown in Figure 21.1. The directory
abbreviations in this figure are given for the UNIX system (first entry) and the Windows
system (second entry). The structure has been simplified with respect to earlier versions of
the Bernese GPS Software.
The root directory ${C} (UNIX) or %C% (Windows) of the Bernese GPS Software Version
5.0 may be defined by the user during installation (e.g., BERN50). Below, we give a
short description of the contents of its subdirectories:
PGM The subdirectory FOR contains all Fortran source files of the programs and the
subdirectory EXE contains all corresponding executables.
LIB The library directory contains the Fortran library libBERN50.a of the Bernese
GPS Software. The subdirectory FOR contains the Fortran source code files of the
subroutines and the subdirectory OBJ the corresponding object files.
INC The include directory contains the Fortran source code files of the modules and
the include files (e.g., COMLFNUM.inc) in the subdirectory FOR. The module files
are classified into four different types. Modules starting with M contain general
information, starting with D are data structure modules, and starting with P are
program-specific modules. I GPSLIB.f90 is the interface file for the subroutines.
MENU The menu directory contains executable as well as the C++-source code for the
menu.
BPE The BPE directory contains scripts and utilities (Perl modules) that are used by
the BPE or by BPE user scripts.
