Implementation
16.09.2002 -as
To save code space the functions AmiSetByte and AmiGetByte
are replaced by macros. For targets which assign BYTE by
an 16Bit type, the definition of macros must changed to
functions.
23.02.2005 r.d.:
Functions included for extended data types such as UNSIGNED24,
UNSIGNED40, ...
13.06.2006 d.k.:
Extended the interface for EPL with the different functions
for little endian and big endian
