TextFile

LOOK

The LOOK program can be used to examine a file within the DFS.  It is
invoked by typing:

    CLI> x look file-name

The program will prompt for a file to examine if one is not specified
on the command line.  Once the file has been opened the LOOK program
prompts for user input with a ">".  You may now type either one or
two arguments.  The first argument is a hexadecimal offset of 8-bit
bytes into the file.  The second argument is assumed to be a decimal
count of 16-bit words to be displayed.  If the second argument is not
provided it is assumed to be eight decimal.  The LOOK program takes
the address and sets the low four bits to zero.  It then takes the
count and rounds it up to the nearest multiple of eight.  LOOK then
displays the portion of the file specified by the modified address
and count as 16-bit hexadecimal words.  To terminate the program type
"BYE" to the prompt.  LOOK is intended for internal use only.
