Excerpt: High Level Assembler (HLA) is an assembly language developed by Randall Hyde. It allows the use of higher-level language constructs to aid both beginners and advanced assembly developers. It fully supports advanced data types and object-oriented assembly language programming. It uses a syntax loosely based on several high-level languages (HLL), such as Pascal, Ada, Modula-2, and C++, to allow creating readable assembly language programs, and to allow HLL programmers to learn HLA as fast as possible. HLA was originally conceived as a tool to teach assembly language programming at the college/university level. The goal is to leverage students' existing programming knowledge when learning assembly language to get them up to speed as fast as possible. Most students taking an assembly language programming course have already been introduced to high-level control structures such as IF, WHILE, FOR, etc. HLA allows students to immediately apply that programming knowledge to assembly language coding early in their course, allowing them to master other prerequisite subjects in assembly before learning how to code low-level forms of these control structures. "The Art of Assembly Language Programming" by Randall Hyde uses HLA for this purpose. The HLA v2.x assembler supports the same low-level machine instructions as a regular, low-level, assembler. The difference is that high-level assemblers (such as HLA, MASM, or TASM on the x86) also support high-level-language-like statements such as IF, WHILE, and so on, and fancier data declaration directives, such as structures/records, unions, and even classes. The HLA language has caused some confusion in the PC assembly language community since its creation in 1999. Unlike most other assembler tools, the HLA compiler includes a Standard Library: thousands of functions, procedures, and macros that can be used to create full applications with the ease of a high-level language. While assembly language libraries are not new, a language t
