     In my particulare application I read the file into an area of virtual 
memory. And then have overlayed various 19 bit fields. One starts
at the start of first byte and goes down. An other starts 9 nine before
that one. And another start at last bit of file and goes back. The three
different layouts of the same memory along with the indianness of the
PC seem to cause problem for people who don't have a PC and DJGPP
C.   Feel free to try to get to ran on something different.  Because it
requires some understanding of the machine to use it.
