It is good to know that pack works. I don't need to dump the binary 
RGB key to one file and the count data to another file and write a
c program to merge them!  

Perl stores its ints at type j/J rather than binary. I have been doing
too much C!!!

Maybe I can spend a few more hour and figure out how to UNPACK a 
binary blob into a string of 1s and 0s. 

Just to make sure I am on the right page here...

    $count=17767;  # C=0x4567=Dec17757
    $c16 = pack("S", $count);  # Pack COUNT to uint16
    $ctest = unpack('S', $c16);  # Pull it back out???
    printf("C=$count = %x, CT=$ctest = %x\n", $count, $ctest);
->
Running C:\bin\bb.pl   Sat Aug 15 01:42:41 2015
C=17767 = 4567, CT=17767 = 4567

Holy Guacamole! The Pack is Back!!
