DASM  is  a disassembler written in the light  of  RESOURCE.   It 
disassembles  to Zilog Z80 mnemonics or TDL mnemonics,  depending 
on  what  options  were set  when  it  was  assembled.   Built-in 
documentation is included with this program as well.

    DASM documentation can be obtained by typing H.  DASM reminds 
you of this when it comes up.  The .OBJ file on this system was
assembled for the Zilog mnemonics.
