For a discussion of high-level assemblers in general, see High-level assembler.

High Level Assembler or HLASM is IBM's current assembler product for its z/OS, z/VSE, z/VM and z/TPF operating systems on z/Architecture mainframe computers. There is also a version that runs on Linux, primarily intended for systems running on a z/Architecture system (this environment is sometimes referred to as z/Linux).
