My apologies again, it appears as me stealing the thread from Wojtek who
asked to the list about bit/byte manipulation within set of bits mapped
to an integer.

The processor is RISC-5 by prof. Wirth, instruction set is very minimal.

The fast system dependant routines are defined in the SYSTEM, which
is pseudo module code generating by the compiler.

Implementors may enrich SYSTEM to suite better their application
needs. At least that is my understanding.

Cheers
