Subject: need directory information

     I am trying to write a program similar to xdir for my cpm 
computer.  I need some information on how to access the directory
tracks on the disk.  Also, how do I use the disk parameter block
to find disk usage information?  I will be writing the program in
C (Software Toolworks c-80).  Any helpful information would be
greatly appreciated.
