Move to Win98 on a new PC 

Jun 2000 
Try out a Win32 port of dia in my application partition at E:\dia 
This expects a valid environment variable HOME, 
http://projects.gnome.org/dia/faq.html#DieOnWindows) 
so change AUTOEXEC.BAT to include: set HOME=E:\dia\home 
No success; give up. (And forget, over the years.) 

Jan 2006 
Try out lily 2.6.5; it sees HOME and puts its cache in E:\dia\home

Aug 2007 
Winsock is corrupted and LSPfix makes it worse, so have no mail or web. 
Instead of reinstalling Win98, decide to move quickly to XP on a new disk 
while still using offline Win98 apps on the old disk. 
Choose Boot-US for dualbooting, but only after having considered/tried 
lots of other methods, during which the Win98 AUTOEXEC.BAT was copied 
from the old disk to the new (by me, or maybe by Win98). 

Dec 2007 
Move from lily 2.8.6 on Win98 to 2.10.33 on XP. 
Although XP has AUTOEXEC.NT as a replacement for AUTOEXEC.BAT, 
it still honors the environment variables specified in AUTOEXEC.BAT. 
(http://en.wikipedia.org/wiki/AUTOEXEC.BAT#OS.2F2_.2F_NT)
These are however only defined for the command console; 
they are not listed by the msinfo32 or SystemProperties-Advanced GUIs. 
Lily 2.10.33 sees HOME and put its cache in E:\dia\home, 
where E: is now a rarely visited partition on the new disk. 

Dec 2009 
Install lily 2.13.9 over deactivated 2.12.1; reactivated 2.12.1 crashes. 
Find two caching folders within %USERPROFILE% but no sign of lily's
active cache, either there or indeed anywhere on C:. Stumped.

See HOME listed by command console's set.
