ALECS: assembly language extensions and control structures
Oothoudt, Thomas Kozlowski · University of North Texas Digital Library (University of North Texas) · 1982
ALECS is an assembly language preprocessor allowing the use of structured programming techniques in MACRO-11 code. Programs are written using standard control structures with normal MACRO-11 code embedded as needed. The ALECS task is used to translate the source to pure MACRO-11 source file which is then submitted to the assembler. ALECS also produces a structured source listing showing the true logical flow of code. ALECS has been used for short subroutines as well as RSX-11M I/0 drivers and an ACP.
