Subject: Microshell, Microtools and Microtree

 You can get Microshell from 

    New Generation Systems, INC
    1800 MIchael Faraday Drive, Suite 206
    Reston, Virginia, 22090
    (703) 471-5598

 I would also check Microtools, and MicroTree. I just bought MicroTree from
 them (ls, cd, pwd, tree, mv, cp, rm, mkdir, rmdir) and it works very well
 (it maps user areas to named directories). I run all three programs under
  MPM-816, but I have also used Microshell and Microtools under CP/M-80, and
  CP/M-816.

 Note that they do not support Microshell under MPM , some things do not work
 well in this environment ( no line editor for example, and script files
 which cross user and drive boundaries don't work well).

  In spite of the problems I found when running Microshell under CP/M-816 
and MPM-816 (you loose the command line editor), the features you can use
make it worth it (input and output redirection, pipes, file and drive paths,
delay constants, customizable prompt, and specially their shell language)
 It beats SUBMIT, XSUB, IF,..., etc. 

 Of course, you can only run 8 bit programs under it.

 I have dedicated one user (0) in one logical drive in my Hard disk 
to COM files and microshell scripts, and have COM versions
of all my important utilities (SQ,LU,USQ,SD,FIND,GREP,etc). I keep the shell
as a detached process and attach to it on a different page of my terminal 
(Televideo 950 with 4 pages) any time I want to run an 8 bit prog.
 
When I got Microtree from New Generations they also included a copy of 
'cd.com' so I could change directories inside the shell. I might also order
the 8 bit version to be able to use 'cp', 'mv', etc.
