This is the Modula-2 source code accompanying Jonathan Amsterdam's article 
"Data Compression with Huffman Coding" in May BYTE 1986.  This code was 
developed under MacModula-2 for the Mac but should be easy to convert to 
other Modula-2 compilers.  Because the Mac allows character names longer 
than eight, the modules have been concatenated into one file with comments 
separating the different modules.  You should break these modules out into 
their own file before attempting to compile them.
