Chapter six (Special Assembler Types) states...
A high-level assembler language (HLA) is a programming language where each
instruction is translated into a few machine instructions. The translator is
somewhat more complex than an assembler, but much simpler than a compiler.
Such a language should not have features like the if, for, and case control
structures, complex arithmetic, logical expressions, and multi-dimensional
arrays. It should consist of simple instructions, closely resembling
traditional assembler instructions, and of a few simple data types.
A high-level assembler language (HLA) is a language that combines most of the
features of higher-level languages (easy to use control structures,
variables, scope, data types, blockstructure) with one important feature of
assembler languages namely, machine dependence.
...
The best known examples of HLAs are the NEAT/3 for the NCR Century computers
[85,86], Wirth’s PL360 [61], a language designed specifically for the IBM 360
computers, Bell and Wichmann’s PL516 [63], an Algol-like assembler language
for the Honeywell DDP516 computer, and BABBAGE [87] a language specifically
designed as a HLA for the GE 4000 family of minicomputers. NEAT/3 and BABBAGE
are HLAs according to the first definition above, while PL360 and PL516 have
been designed in the spirit of the second definition.
This is real life folks, not the make believe crap you've been listening to.
