[Oberon] FPGA - Little Endian & Bit numbering

Here BlackBox is ahead, as usual. From the CP Language Report:

10.3 Predeclared Procedures

Name     Argument type   Result type   Function
BITS(x)  INTEGER  SET        {i | ODD(x DIV 2^i)}

I used BITS a lot in my data processing. It is extremely useful.

One more example why upgrading Oberon to CP should have been done long ago.

It's odd, however, that there is no (non-SYSTEM) procedure for
converting an integer back to a set.
