You know when I was a teacher I could flunk those who refused to work. When I was a coach I could bench them. When I managed a large aquatic facility I could fire them. I can’t do any of those things to you. You are all volunteers! So what motivation do I have to get you to serve? Very simple, I have the words of God that I presented to you this morning – His command and the great promises of His grace and your reward. If you are not excited about being directly commissioned, gifted and empowered by the King of the Universe to do His will, there is not much more I can do to get you engaged.

Mac Number conversion (LSB/MSB)

Heres one for the thinkers...I need a couple of functions (my brains in a
fog lately...).

I am reading a file which has binary numbers stored in LSB/MSB format so
some bytes read in will look like this :

73 0 0 0 27 01 0 0

Those are basically TWO longs. The first is 73 0 0 0 (LSB->MSB) and then 27
01 0 0 is the second one. If memory serves right, the Mac stores in MSB/LSB.

I just bet someone has a real fast efficient way of turing those digits
around (they are in binary in the file). If I was still in Z80, I'd do a
rotate thru the carry. I'm not.

But I have a lot of processing to do with longs and words stored in this
format.

Suggestions?
