Assembly language is not a proper "programming language" per se, but rather a tool that allows you to write machine code using short, semi-human readable memenomic instructions and link the into an executable, as an alternative to having to write streams of ones and zeroes and load them into memory. This effectively means that not only do each microprocessor family have their own assembly language format and instructions but also each processor version inside that family has its own instruction variations, but in addition to that different assemblers may use different mnemonic substitutes for each processor instruction.

A list of OS/2 assemblers and assembler related tools

OS/2 disassemblers

OS/2 development systems with built in assemblers

Aids

  • FWKTL - Allows OS/2 to run COM like self modifying code

Libraries, bindings and stubs

Local articles

Tutorials and other learning material

Links

  • Sandpile.org - Lots of info on i86 and AMD64 instructions.
  • The Art of Assembly Language Programming - An often referenced 80x86 Asm on-line tutorial and reference, note though that the examples are in a HLA format, a specific type of assembly not available for an OS/2 toolset.

Mailing lists & forums

  • Assembly Language Programming - On Yahoo groups - very low volume list but with a large group of subscribers so it can kick into life unexpectedly.

Standards

Unlike most other languages the assembly language is not an artificial language that requires standardisation but rather an implementation of a practical reality that came into existence when a specific CPU was designed and manufactured, so the standard is the actual documentation of a hardware implementation. That means for 8, 16 and 32 bit processors the "standard" are the processor and programming manuals from Intel while for 64 bit assembly language you need to look towards similar manuals from AMD.
