There is an ASM Integerated programming enviroment for Linux called
'asmide'
Try: sourceforge.net/projects/asmedit

Linux will give you 2GB of program/data space in a flat memory model
The ASM IDE package includes how-to info on making Linux system calls from
ASM.

For X86 Linux/DOS/Windows, try 'www.ml1compiler.org' For a basic like
macro language that compiles directly to asm sourcecode. It's a macro
compiler that allows custom command design and optimization. It compiles
to the ASM of your choice, (you write the macros) or to X86 asm (macros
included). The compiler comes with the NASM assembler which uses the
simple Intel syntax and leaves out all 'offset(label)' type stuff. NASM
has no type checking, which allows you to do whatever you like without
having to trick the assembler into assembling it. The ML1 compiler has
user defineable type checking, and it calls NASM for assembly. The
compiler includes system routines for DOS (all sourcecode) which can be
re-programmed for any OS. It's free.
