PROGRAM HEXDUMP; æ$A+,R-,S+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	å
æ 16 bytes in hex, and then the same bytes in ASCII, if they	å
æ are printable. On running the program, you must specify the	å
æ name of the disk file to be dumped, and the name of the disk	å
æ file or logical device (CON:, LST:, etc.), which is to reci-	å
æ eve the dump. The dump can be halted temporarily by pressing	å
æ any key, or aborted using ^C.					å
