This is the parameters program, which takes the output of the atlas block command, for a classical group, and gives parameters in Dan Barbasch's notation. INSTRUCTIONS: 1) Download parameters.tgz to a unix system 2) tar xvfz parameters.tgz to unpack it 3) chmod u_x parameters to make it executable 4) Give the command "./parameters -h" for a help file. You can also download the file parameters alone.
