ADDPATH.BAT - An extension to the DOS PATH command
    ~~~~~~~~~~~
    During development, it is often necessary to modify the search path. This
    can be a tedious task, particularly if small additions are to be made to a
    search path which is already several directories long.

    ADDPATH allows the addition of a prefix, a suffix, or both, to the search
    path as well as manipulation between the new and previous search paths.

    Full help is given by typing just ADDPATH.

    This program keeps copies of both old and new search paths in the
    environment. Should the computer complain as a result "Out of environment
    space", it may be necessary to add the following line to CONFIG.SYS:

      SHELL=COMMAND.COM /E:1024 /P   (Refer to DOS manual for further detail)
