The OS has error messages in the form of B_JUMP routines. You call bjump on them, handing control back to the OS, and after the user selects Quit or Goto you're out of the program. I wouldn't recommend using it though -- might even be simpler to just write your own error message. ERR:SYNTAX isn't really informative anyway

Thx for reply =]

Already knew about the b_jump routines.
Qwerty.55 already adviced me to use the JError one.
The problem is, that it seems to be just an error displayer and nothing else.
What i need to do is, after exiting, forcing the system to point to a specific token in a specific prgm.
I know it's possible, since it's one of DCS features.

Yeah, the JError routines basically just display the error messages. If you want it to jump to a specific location in a program, you need to find that location yourself, open up the edit buffer, load the program in, and set up the edit pointers to point to that location.

progress : 80% (6357 bytes)

left to do before initial release :
- variables initialisation
- automatic differentiation of executable or read-only data
- main loop (compatible with pass 1 & 2)
- final size check before writing
- goto on errors handling (automatic unarchiving if enough free ram to do so)
- z80 include prgm (progress : 95%)
- 8X+ include prgms (progress : 0%)
- code testing & optimizing
- readme file

Prgms are assembled correctly and all the features seem to work as intended.
I'm facing one problem now : the whole process becomes really slow when huge prgms are included in the source.
Looks like the optimization part is gonna be more than just optimization =[

Hey, this is pretty cool. I actually like the fact that it uses the built in program editor. Keep up the good work. ^^

This is amazing ! This is one reason why I gave up ASM: not on-calc.
With ASMdream, I wouldn't have given up (maybe)!

* ZTrumpet looks at Mimas...

I didn't know about it, but it is too late, now, I've given up.
Thanks anyway.

Some little news for those interested in this not-so-dead project :

The conversion of my source from prgm to app is going good.
However, it requires a lot more rigour, since i have to handle memory swapping in bank b (the price to pay to be able to read archived prgms).

Also, decided to abandon the idea of treating z80 ops as macros (which was working, but definitely too slowly).
Instead, they're gonna be hard-coded, following an horrible (but lot more efficient) algorithm i'm about to give birth.
Anyway, the way i'm making it, the whole thing will fit in a 1-page app.

While i was dealing with z80 ops, i noticed some errors in the well-known undocumented z80 table provided by joe wingbermuehle (tasm compatible).
I'm posting the thing here, since i thought creating a dedicated topic was, let's say, too much :

replace :
OUT   F,(C)   71ED   2   NOP   1
by :
OUT   (C),F   71ED   2   NOP   1

replace :
DEC   IYH   24FD   2   NOP   1
by :
DEC   IYH   25FD   2   NOP   1
This one is especially dedicated to those who never found the origin of the bug in their source =]

Nothing thick to show for now, except maybe my new splash :
