1.  General Description

      The File Dump (FDUMP) program reads, formats, and prints a disk file
to the user's terminal or to another disk file.  The input file is read
in clumps of 512 bytes and is printed 32 bytes at a time.  The print line
consists of the hexadecimal representation presented as eight 32 bit
longwords, followed by the ASCII representation of the same data as a
32 character string.

2.  Execution

      FDUMP is invoked by entering the following:

               RUN BUILD:[BLDUTIL.RUN]FDUMP

The program will prompt for the following:

      1. input file name - the name of the file to be dumped, as fully
         qualified as necessary.
      2. output file name - the name of a file into which the formatted
         output will be written (UNIT 11).  If the return key is pressed
         without entering a name, the output will be directed to the user's
         terminal.
      3. block numbers - the starting and ending blocks to be dumped.  Block
         number 1 indicates the first 512 byte block, block 2 the second 512
         byte block, etc.  These values are entered as two digits separated
         by a comma, e.g. 1,4 will cause the first 2048 bytes to be printed.

3.  Notes

      If the input file cannot be opened, a message containing the I/O 
status and the IOSB content will be printed, and FDUMP will terminate.
Unprintable characters in the ASCII string are represented as periods (.).
Lines that are the same as the previous line are not printed, but are noted
by the phrase "LINES xxxx THRU yyyy SAME AS ABOVE".
