     NAME
          wall41 - a program to extract information from an HP41 Write
          All file

     SYNOPSIS
          wall41 [-k [ key_file ] ] [-b buff# [ buffer_file ] ] [-r [
          register_file ] ] [-s [ status_file ] ] [-p program_name ] <
          writeall_file

     DESCRIPTION
          An HP41 Write All file is a dump of the entire contents of
          user memory, including user data, user programs, buffers,
          key assignments and the status registers.  wall41 reads a
          Write All file from standard input and extracts one or more
          of these sections from it. The extracted data is written
          either to standard output or to the specified file. In turn
          this information can be decoded by other filters in the LIF
          Utilities package.

     OPTIONS
          -k [key_file]
               Extract the KARs (Key Assignment Registers) in a format
               suitable for decoding with key41. If an output file is
               not given, the data is written to standard output and
               can be piped directly in to key41

          -b buff# [buffer_file]
               Extract the contents of the buffer area with id buff#.
               If buffer_file is not specified, the data is written to
               standard output.

          -r [register_file]
               Extract the user data registers as an sdata file. If no
               output file is specified, write the data to standard
               output, suitable for piping to the sdata program.

          -s [status_file]
               Extract the status information (user stack, alpha
               register, user flags) to the specified file, or, if no
               file is given, to standard output. The program stat41
               can be used to decode this information.

          -p program_name
               Extract the user programs to files called
               program_name.001, program_name.002 and so on. The
               program_name must be specified, this option cannot
               write data to standard output.

          -?   Print a message giving program usage to standard error
               and exit.

     REFERENCES
          The format of the HP41 Write All file is undocumented, but
          as it is simply a dump of all user memory registers in the
          logical order, most books on synthetic programming which
          contain the format of HP41 user memory are a good reference
          on the data contained in a Write All file. Information of
          the format of Key Assignment Registers, HP41 user programs,
          data registers, etc can be found in the same books.

          Two useful references are :  Extend Your HP41 (W. A. C.  and
          The HP41 Synthetic Programming Quick Reference

     EXAMPLES
          If all1.w41 is an HP41 write-all file, then

          wall41 -k < all1.w41 | key41

          will display the key assignments to standard output.
          Similarly

          wall41 -p program <all1.w41

          will extract user programs to files called program.001,
          program.002, ...
