GEMDOS.BAT  -  A user friendly DOS shell for GEM
  ~~~~~~~~~~
  The  GEM environment,  as in  the GEM  Desktop Version  2.0 given  with  the
  AMSTRAD  PC1512, does  not provide easy means with which to type in commands
  not covered by its own pull-down menus.  A notable omission is the inability
  to  look  at  the  contents  of text files,  e.g. the DOS TYPE command,  and
  others.

  To  cover for  the above  shortage there  is a DOS shell command, «ENTER DOS
  COMMANDS»  in the  «OPTIONS» pull-down  menu. This  command, however, is not
  user  friendly, since  it always  shells out into the root directory, C:\ in
  my case.

  The  GEMDOS.BAT  file  serves to overcome the above limitations by providing
  the following features:

  1.  Double clicking  on its  ICON in its specified directory  (A:\GEMAPPS in
      the provided example) will cause a shell into the GEMAPPS directory.

  2.  Copying it  into any other directory (i.e. dragging with the mouse)  and
      then double clicking on the new copy, will cause a shell into the chosen
      directory.   The new copy of the GEMDOS.BAT  file will be  automatically
      removed from the chosen directory.

  3.  In either  of the  above two cases, this DOS shell utility allows typing
      in a  DOS command whilst still in the GEM environment.  This  command is
      typed into  the GEM «ENTER PARAMETERS» window which appears  immediately
      after double clicking on the ICON.  The command may be constructed of up
      to 10 words (9 interleaving spaces), inclusive of all its usual switches
      and parameters;  however, piping  and redirection symbols  " | < and > "
      are not permitted.

      The TYPE  command, probably the most common use for this batch file,  is
      treated  with  the  MORE  filter,  so  as  to  get  one  screen  full of
      information at a time.


  THE SPECIFIED DIRECTORY:
  Since  the program  needs to  know which copy of GEMDOS.BAT  it is to delete
  during  a shell  and which it is to keep, its default directory is specified
  in line 5 of the file. It takes the form:

      A:\GEMAPPS\GEMDOS GemDoS %0 %1 %2 %3 %4 %5 %6 %7 %8 %9

  The underlined part of which may be edited to indicate the correct drive and
  directory,  e.g.,  C:\GEMAPPS,  C:\BATCH,  etc.
