Hi, there.

Please let me add that as someone who is learning assembler for the first
time and has only been writing it for two months, I love the AT&T syntax.

One neat feature is that it looks like standalone GAS programs in DJGPP
which use C functions for i/o rather than MS-DOG specific interrupts might
run in Linux or Coherent, for example, with only a few changes.

Writing such standalone assembler programs is for me one of the high
points of DJGPP.

BTW, about a month ago, Eli advised that crt0.o would be the key to the
problem of standalone GAS programs. The solution of using C-style i/o and
assembling like this

gcc -o myprog.exe myprog.s

has proved him right.

There are a few differences between DJGPP and some other "Gintel"
environments (i.e. GAS + Intel i386). For example, a Linux "hello.s" seems
to use '.global main' instead of 'global _main', and there may be a
different convention in terms of restoring %ecx.

At any rate, portability issues aside, I find AT&T a user-friendly
standard. Of course, alternatives such as NASM meet some of the needs of
people with different tastes or problems to solve.

Most respectfully,
