If the SW is useful being run on the FPGA HW then one has still the possibility to „port“ the SW iso „throwing it away“.

While porting several Oberon-2 code to Oberon-07, I found (looking at EXIT, LOOP, RETURN): in most cases it is more or less straight forward, and only sometimes (sudden RETURNs in nested loops) a bit harder. I find the resulting code almost always much more readable.

Some of the porting techniques I used:
- break up in smaller functions
- introduce error or state variables
- Introduce routines for 16bit entities, if „old“ INTEGERs are really only 16bits.
