Novice that I am I have two unrelated problems to solve.  The first involves
expanding a bitmap.  For example, I have an N x M bitmap that I need to
expand by A to get a resulting AN x AM bitmap.  The vertical I can handle once
I get the horizontal expansion.  By way of example if I have an 8 X 14 bit
matrix and the first byte is 01101011 and I need to have it expanded 3 times
so that the resulting three bytes are 00011111,10001110,00111111, where each
zero is replaced by three zeros and ditto for the ones.

Is there a general algorithm for handling this type of expansion?

The second problem is probably simpler.  I have pretty much determined that
Turbo C stores integers with the least significant byte first.  One file
structure that I'm accessing does it most significant byte first.  I've used
a macro to get around the problem of printing out the value of this integer
but was wondering for the sake of manipulating the value if there is a standard
structure or "typedef" that can be used instead.

Thanks beaucoup,
Bob
