Hiya,

 Sorry about the big title :-(

 I think this one's probably already on the dev. line by inference but I
thought I'd better re-iterate it for logging purposes as it may be relevant to
recent queries.

 More to the point I have some code that should eliminate the problem from a
design concept but it requires reasonable tinkering with the code and I'm not
sure if this might be redundant if there's a newer version imminent.

<Summary>

 Although the real life actions of removing a package and installing a package
are "similar" (i.e. the actions and processing of the actual commands should be
the same, it should just be the bits around those actions that have
significance), the code, as it stands, doesn't mirror the similarity. 

 Essentially: The removePackage function doesn't include environment variable
handling whereas the installPackage routines DO. This is just a "missing code"
thing but it has some awkward effects.

 I don't think many people would have noticed this except in boundary
conditions. It's one of those hard to find ones.

 As the environment variable handling is applied to the whole environment
around WPKG.JS and most people are using %SOFTWARE% strictly as a pointer to a
single software repository and as it's very likely that all removal actions
have been preceded by an install action, the environment has most likely been
"prepared" accurately by the script but not strictly in a logical way in
response to the XML settings and package independance ideas.

 As I mnetioned I've got some code ideas but they need some explaining so I'll
be back soon with attachments and a summary of them. There's many ways to skin
a cat...

Regards,

Keith
