 32bit ASM-Code under DOS

Hi NG,

i've an 386 handheld DOS PC.
I've implemented an algo which uses 32-bit (eax,ebx,...)
I have to implement this in an existing VB DOS Projekt.

Q1: Can i execute 32-bit code in DOS (with an 386)?
Q2: Does anyone knows an 32bit assembler/compiler which create VBDOS
compatible .obj-Files

Thanks in advance,
Klaus

You can execute 32-bit instructions, but in 16-bit segments.
(This means you're still limited to 64K segments unless you're
using a DOS-extender, which doesn't sound likely on your handheld).

MASM or TASM should.

Do you want to execute 32bit code (=protected mode) or just using the
32bit registers in 16bit code? Both works on a 386.
16bit code with 32bit registers is not a problem at all, but 32bit
code would require the use of a DOS extender or your own
pmode-switching routine.

I don't know what is VBDOS, but if you're looking for 32-bit compilers that
can generate DPMI 32-bit apps for DOS, then there're a few of those:
- DJGPP http://www.delorie.com/djgpp/
- Digital Mars C/C++ Compiler  http://www.digitalmars.com/
- FPK (FPC) http://www.freePascal.org/
- TMT Pascal http://www.tmt.com/
- Virtual Pascal http://www.vpascal.com/

Good Luck
