I'm a newbie in learning assembly language now. I'm using text The Art Of Assembly Language now.But I've met a big problem!!!
I can't assemble & link the source file correctly.For example ,in chapter 5
,the Pgm5_1.asm file.I can't assemble it any way.
Please help me!!! Tell me why,and what should I do,please!!! :(

Art Of Assembly: 16bit dos code.
masm32 is geared for 32bit windows programs. You will have
to get a 16bit linker if you want to produce dos programs - and
you should ask yourself if you really want to do that.

And you should not crosspost.

whitebird,

f0dder is right, you need a 16 bit OMF linker to build 16 bit code, 32 bit MASM code is COFF.

It can be downloaded at Iczelion's site or if you can find it, in the Microsoft site.

whitebird,
if you fire up your newsreader and point it towards the news://microsoft.public.masm]news://microsoft.public.masm group, then you will be able to talk with the author of AoA directly, as he frequents that group on a daily basis.
