Similar to C/C++ programming the programming of VBA is based on the DLL
concept. To enable access to GeoCOM the special module

3.3.1 Data Types in VBA - General rules for derivation
This subsection gives a summary of general derivation rules VBA-parameters
from C-data types. Basically the C/C++ - data types are given in a C/C++ notation
before they are used in a RPC-description.
If the appearance of a VBA data type does not follow the general rules then they
are described explicitly.
In general, the following rules can be applied:
Numerical data type
The numerical data types correspond to the C/C++-parameters in value and
range as close as possible. If it cannot be replaced directly then the best
possible replacement will be taken.
