download the debugger version of dosbox(development forum) and you have a good starter debugger which is undetectable by programs.

I knew about the debugger version of DOSBox but it sounded like it might be more trouble than it was worth. Can it assemble (or do you have a recommended assembler that will work fine under DOSBox)? Can you recommend a good list of DOS interrupts (I've looked with Google and checked out an old book but I want more [maybe I'm a glutton for punishment 😀])? thanks

Most debug.com/debug.exes should work, maybe you can get the one
from novel dos or similar which is a bit more advanced than the msdos one.

DOSBox can't assemble code as easily as debug, so for small tests it might
be feasible. For larger things some integrated assembler is recommended,
like the one from turbo pascal/c or whatever.

Interrupt lists: search for ralph brown's interrupt list.

wd: I've seen that page before (though it seems I didn't fully appreciate it).

Like I said, DOS interrupts. Win9x systems are coninuing to be prevalent and DosFreak posted something (I forget what and where) about DOS being done and Linux being a moving target or something like that and realizing those two things has really restored my confidence to try to learn non-NT x86 (really 386+ DOS 4+) assembly language. I'd really like a cohesive, coherent list of "INT 21h" (as listed in anicent DOS texts) functions and similar things (other DOS interrupt sub-functions, if there are any that aren't in int 21 [besides int 10] that are important). TIA

[edit] also, I didn't mention that Vista (at least my copy) has Debug, and I didn't ask Qbix where (s)he (or whatever the trendy gender-nerutral pronoun is these days) got that avatar GIF

Somehow i got the feeling of being ignored. Well.

wd: I tried running my Win95 Debug in DOSBox and it gave me a DOS mode error (the same one I got for MODE as per my other thread). But if DOSBox: Debug Edition or whatever it's called can assemble, I'll take it (I wasn't expecting to write an IDE in assembly or anything, just get the hang of it, though if it doesn't handle most [really all the interesting] DOS interrupts, I think I'll pass).
thank you

Dunno about 95's mode.exe, try those from ms/pc/whatever dos,
suppose the one(s) from freedos work as well.

I already got that straightened out (Text modes with more than 25 lines and the internal ANSI support); "set80x50.zip" (which is pretty good) and a reference to ANSIPlus (which I'd rather not mess with), but anyway as I said I'm not climbing the walls over that, or this for that matter, just my normal constant curiousity.

I just realized now that wd referenced Mr. Brown's int. list & not Qbix
sorry
still getting the hang of this
appreciation to all and to all a good Halo 3

Can you fall off the floor?
