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.
