This happens only if asm56000.ttp is launched from
DESKTOP.INF and its arguments are pushed to program
basepage (which has worked fine for many other programs).

If one runs asm56000.ttp manually from GEM desktop and
gives the arguments to TTP dialog, then Fopen() is for
"EQUATES.ASM" file.

If one runs things through Tomshell, "DECODER.ASM" is
Fopen()ed instead, same as with floppy image.

In all cases with GEMDOS HD its missing creation of
"DECIDER.CLD", and does Pterm(-1) quick afterwards.


I even started to wonder whether Pexec() native assembly
implementation in Hatari cartridge code could be causing
some issues, as I've checked nearly everything else...

Program doesn't seem to have any relocation data though
(after I stripped it):
--------------------------
$ gst2ascii mp2_inc/test/asm56000.ttp
Reading symbols from program 'asm56000.ttp' symbol table...
TOS executable, DRI / GST symbol table, reloc=0, program flags: PRIVATE 
(0x0)
Program section sizes:
- text: 247456
- data: 12868
- bss:  5298
--------------------------

PS. asm56000.ttp startup does one Fforce() call, but
it's just:
  GEMDOS 0x46 Fforce(2, 65535) at PC 0x59C84

I.e. mapping GSH_AUX (serial) to GSH_BIOSCON (console),
which is handled by TOS, not GEMDOS HD.  After that
there's some polling to see whether AUX has any input.
