- Lab 2 (solution):
  - Here is what you should have done:
    1. Dump the lines in the source code for the `STATUS` command (`$NMROOT/nxm/sys/intr/Status.java`) using the package syntax.

           nM> stat nxm.sys.intr.Status.java /d=-1

    2. Form the path for `apenny.prm` in `AREA=DAT`, `OPT=SYS` in a platform independent way. Then use the `if` command to check for its existence from the shell.

           nM> fname filename NAME=apenny EXT=prm OPT=SYS AREA=DAT
           nM> if filename FEXISTS
               or
           nM> if nxm.sys.dat.apenny.prm FEXISTS
               or
           nM> file name fullname (^env.nmroot,nxm,sys,dat) apenny prm
           nM> if fullname FEXISTS

    3. Can you list the files in
       original: `http://nextmidas.com/nm/nxm/sys/dat/` (currently unavailable)
       alternate: `file:///opt/midas/nxmlatest/nxm/sys/dat/` (where /opt/midas/nxmlatest is a softlink to your local nxm installation)
       Why or why not?

           Yes. The nextmidas.com web server is configured
           to provide a directory listing, but this may not
           be the case with all web servers.

    4. Can you `status` the file
       original: `http://nextmidas.com/nm/nxm/sys/dat/apenny.prm` (currently unavailable)
       alternate: `file:///opt/midas/nxmlatest/nxm/sys/dat/apenny.prm` (where /opt/midas/nxmlatest is a softlink to your local nxm installation)
       Why or why not?

           Yes. The nextmidas.com web server, like most web
           servers, is configured to allow access to this file.

    5. Use the `NOOP` command to copy the first half of the elements from
       original: `http://nextmidas.com/nm/nxm/sys/dat/apenny.prm` (currently unavailable)
       alternate: `file:///opt/midas/nxmlatest/nxm/sys/dat/apenny.prm` (where /opt/midas/nxmlatest is a softlink to your local nxm installation)
       to a file `halfpenny.prm` in your WRITE aux.

           original: nM> noop http://nextmidas.com/nm/nxm/sys/dat/apenny.prm(0:64) halfpenny.prm
           alternative: nM> noop /opt/midas/nxmlatest/nm/nxm/sys/dat/apenny.prm(0:64) halfpenny.prm

       (Note that the 64 is exclusive and it will copy elements 0 through 63 to the new file.)
