 Sorry, it has nothing to do with code moving, I've debuged it and I've
found there it is a bug causing the bytes 2nd and 3rd to be incorrectly
encoded (from 93h,5h to 94h,6h)  (don't know if any other bit is bad
encoded too). It's a very small COM, I haven't tested com>32k, and 16
bit exes seems to work.

 I'm sending it attached. It's called TXT106.COM

-----------------
BTW: What the hell does things like this mean?:

        mov    bx,7114h
        jmp    bx       (instead of just jmp 7114h)


7114h:  call   depack
        ret
depack: [...]           (instead of depack: [...]
                        and jumping to program with depack's ret)

 Aren't you optimizing on space? (I haven't seen all the code, maybe
        there's a reason, but just can't imagine it ;-)

Ok, but I advise you: this is big. Here it comes too...

 I've done some test with various configurations. There's no problem with
-S option, but default (using PMODE), tested with my 5 configurations, gives
the following:

1- defa: QEMM            > Executes (color screwed) and system unstable at
                                exit (Trap handled by QEMM when trying to
                                execute any 32 bit program, reboot)
2- free: (Nothing)       > Executes (color screwed) and system ok at exit
3- hime: HIMEM           > Hangs with blank screen, needs reset
4- prog: QEMM            > (same results as 1)
5- swat: HIMEM + SWAT386 > Executes (color screwed) and system ok at exit

 I'm also sending my CONFIG.SYS and AUTOEXEC.BAT files, in case they help

 Therefore I think -S should be the default, because it's more compatible
and smaller.

BTW: I'm sending it ARJed, but if you prefer, I'll send stuff compressed
with a better one next time (if any), e.g. UHARC, ACE, etc...
