Overview

HLASM was released in June 1992 replacing IBM's Assembler H Version 2. Despite the name, HLASM on its own does not have many of the features normally associated with a

, but does offer a number of improvements over Assembler H and Assembler(XF), such as labeled and dependent USINGs, more complete cross-reference information, and additional macro language capabilities such as the ability to write user-defined functions. While working at IBM, John Robert Ehrman created and was the lead developer for HLASM and is considered the "father of high level assembler".
