I wish I could sound really technical about this, but I can't, so, he's what I have to say: This rocks! This might lead to the cross compilation of programs for all calculators so that a programmer would only have to learn one language and then be able to port to all calcs...wouldn't that be cool? Well, that's all i have to say...bye.

Imagine....you can write a program in C++ for the 89, and then you can just slap it into a converter (assuming it fits) and.....BAM! 82, 83(+), 85, 86, 92(+) all get another program.

begin
writeln('But what this world really needs is a Pascal version that'll work with the 83+!');
end.

Can't get this to work - it keeps on warning me that the "ti-85." file is missing (and no, that is not a typo of "ti-85.h").

Then when I try to assemble it with doors.bat I get a relocatability error with these lines:
(user macro) line 1
soli.asm line 220
451 ___ADDR set ((PROGRAM_ADDR-$1000)&$7FFF)
^ Relocatability error.
^ Illegal forward reference.

The missing file problem occurs because Source Guru expects the filename to be quoted, and thus will remove the quotes, even if they're not there.

The relocatability error is a bigger problem. The reason has to do with the way addresses are converted. In order to save execution time, references to a constant address are converted to their true values at assembly time. However, if these involve labels it will cause problems since the label addresses themselves are values computed by a distance inside the program. The end result is that any program loads data from labels directly into registers won't work. This breaks most Usgard programs but isn't an issue for ZShell ones. The only significant Usgard program I know of that works is Avenger, which I haven't released in converted form since I don't have the author's permission.

This will be solved in the next release of Source Guru, which will evaluate addresses itself instead of passing them on to A68K to deal with. This also will allow the self-modifying code handler to be done, since I can tell whether references are pointing into the middle of instructions.

I have been getting duplicate symbols and no such op-code and operand size error. What causes those???

Does this mean Joltima 89 any time soon?

He he. You ti92 owners are lucky. The only reason I don't have a ti92 is that they're banned in highschools in the UK. Noooooo! (They're classed as computers).

Anyway, you'll never get ti86 programs to run on the ti92. (Note: don't take this seriously. I know it's possible. I just want to encourage someone to try and prove me wrong, then I can get a ti92).

Sounds cool. ION86 is cooler (except the interface - no offence guys).

I recently for some reason installed rom version 2.03 on my friends calc. I have sent DoorsOS II 0.93 to the calc, and i run it, it loads the pic but when i hit enter it has a black line go accross the top and it freezes, the only way to get it back to ti-OS is to take out the batteries! this is really annoying and i can't figure out what to do. i tried the old version of doors and it does the same thing. my friends calc is HW2 if that makes a difference. any help would be greatly appreciated.

Thanx

Well, you're on the wrong message board for that one...but I had the same problem too on my friend's HW 2 AMS 2.03 calc.. I emailed Xavier about it, so look forward to an updated version of Doors to handle that error.

ok, thanx

aye, good job patrick! i will be hella happy when the 89 version of guru comes out. but will all of these changes be made so it runs on all roms (including ams2.03)? if not, what ROM's will it not work for.
thanx man

The converted are for DoorsOS II, and as far as I know they should work on any calculator that DoorsOS II can run on.

when I try to send jezzball converted with the new source guru to the 89 it doesn't send

I want to say congratulations! I was about to start a HUGE upgrade of the Calculus Toolkit 85 version to an 89 version. We are talking about 21 subroutines, plus the main program. This compliler may be what we need, even if I still have to translate from 92 to 89.
