Re: Retrieving original value of enviroment variable HOME

Hello, Hans,

I've just renewed the Ctx Beta installation, but 'environment.oldhome' 
seems be unavailable.

Was I "too quick" with renewing Ctx?

Testing sample:

----
\starttext
   Ahoj
   \startluacode
     context(environment.oldhome or "??")
   \stopluacode
\stoptext
----

- prints "??".

I also attache the "status-of-update.lua" and the batch 
"first-setup.bat" (maybe a bit obsolete, but working so far) I used to 
renew Ctx.

Also result of "dir /s" is available here (~84 k packed):

What am I doing wrong?

Best regards,

Lukas
