In the preface to his excellent textbook Algol 68: A First and Second Course, Andrew McGettrick writes: “This book originated from lectures first given at the University of Strathclyde in 1973-4 to first-year undergraduates, many of whom had no previous knowledge of programming. Many of the students were not taking computer science as their main subject but merely as a subsidiary subject. They, therefore, served as a suitable audience on whom to inflict lectures attempting to teach Algol 68 as a first programming language.”
