High Level Assembly Language (HLA) is an educational language created by Randall Hyde and documented in his book Art of Assembly.

High Level Assembly Language (HLA) is a procedural language that compiles to x86 machine code developed by Randall Hyde to help students learn Assembly language. HLA incorporates high level programming language constructs including multi-dimensional arrays, ENUMs, bounds checking, functions, and a standard library. This "High Level" C-like code can be mixed with a subset of x86 Assembler inline.
