In trying to concatenate two eight bits unsigned values (msb, lsb),
ASH (ORD (msb), 8) + ORD (lsb), where msb, lsb are SHORTCHAR generates 8
bytes of code less than
SHORT(msb * 256 + lsb MOD 256), where msb, lsb are BYTE.
Both work fine, but both are tricky.

I wonder why BYTE was not defined as 0..255, instead of -128..+127?
Those signs are an annoyance when acquiring serial port BYTEs.

Cheers,
René Dorta.
