PROGRAM hexdump; æ$K-,R-å

æ This program will output a hex dump af any disk file. Each    å
æ line shows the address of the first byte of the line, then 16 å
æ bytes in hex, and then the same bytes in ASCII, if they are   å
æ printable. On running the program, you must specify the name  å
æ of the input and output files on the command line. The output å
æ file defaults to the console, i.e. the CON: device.           å
