I agree here.  This only helps if the "Out of Environment Space" error
appears when trying to set an environment variable.

What you are confusing here is what DOS can internally handle for an
environment variable and the DOS command line buffer.  The command line buffer
is around 128 characters long.  This is what limits the size of the
environment variable when using the SET command.

DOS itself can handle a PATH variable longer than 128 characters.  The problem
is how to get the value set in DOS's environment space.  I have seen one or two
utilties which directly mess around with DOS's internal environment space to
create very long PATH variables.  Unfortunately I do not remember the names of
them{
