Datatypes

The datatypes are float, int and string.

int	integer value.
float	32-bit float value.
string	80 character string (null terminated).

There are three different tables in which a variable can be declared: local,
global and extern. A local variable is known inside a function, a global is
known in all functions in a file (with include-files), an external is known
for all files executed in a session.
