Hi Bertho,

I've spent the last three hours writing a tiny COM program that moves  
COMMAND.COM's environment block to the lowest address possible (using  
DOS's "low memory first fit" strategy). Unfortunately, it does not seem to  
be able to find the environment block if used in AUTOEXEC.BAT after HIMEMX  
and JEMM386 were loaded in FDCONFIG.SYS (I only tested both at the same  
time, so I don't know which one causes the problem), but it works if run  
after AUTOEXEC.BAT has been processed (for some reason - but by then you  
may have TSRs loaded between COMMAND.COM and its environment, which may or  
may not be OK for your needs) or if those two drivers are not loaded.

So for example, without HIMEMX and JEMM386, FreeCOM will allocate its  
environment block at e. g. segment 9F7F, but after running the program,  
the environment block will reside at segment 23B4, almost immediately  
after COMMAND.COM (it depends on the order in which you load TSRs).

Please contact me off-list if you want to try it out.
