Re: Binary Bit Map

He... I have an example (nah.. two) of Hi-/Lo endian here:

www.Think400.dk/adhoc_5.htm#eks0001

reading one byte from a PLC in hex, converting it to decimals and then again
converting it to binary and then flip it from High-endian to Low-endian.

Mark,

You should be aware that most computer languages (including, I think, RPG)
will refer to the first bit as bit 0 and the last bit as bit 7 (rather than
1 to 8). I've been caught by this in the past (thinking some documentation
is talking about one bit when they're actually talking about a different
one). And don't get me started on big-endian and little-endian (feel free to
Google these terms to get even more confused :-()
