[Coco] Re: Path command wasRe: OS-9 LVL II

[Robert Gault]

The primary problem seems to be that we are dealing with a hack to shell 
rather than a change to the OS-9 system. We probably need a change to 
one of the managers for something like path= to work with all possible 
combinations of intermediate code modules.

As for what Pascal created, if Ident indicates Test is ml code then I 
don't understand what the difference is between Test and dEd regards path=.

It won't stick unless the last line in the startup file is
i=/1
