Summary: A non-kludge method for large PATHs



The 'legitimate' way to create long path strings is to use the lastdrive
option in config.sys and the subst command.  Example:
  lastdrive=k            (say the 'real' last drive is d:)

  subst e: c:\bin\util
  subst f: c:\bin\lang
  subst g: c:\bin\games
  subst h: c:\bin\filter
  subst i: c:\bin\editors
  subst j: c:\bin\etc
  subst k: c:\bin\etc\etc
  path=d:\;c:\dos;c:\;e:\;f:\;g:\;h:\;i:\;j:\;k:\

I don't recall off hand just what the limit on lastdrive is,  but it can
go a very long way in solving large path problems.  See the DOS manual
(3.0 or beyond...)

One word of caution - if you use DOG 1.01 to optimize your disk with
substitution active,  DOS loses place of any directories which have
moved.  I find it necessary to reboot after such activity.
