Thanks.

Aho et al. was also given in Modula-3 which was perfect since Pascal-derived languages clearly motivate the why and the guts of the algos. C obscures them (too focused on pragmatism).

Wirth's DS + A = P book was also written in Modula-2, a better, real-world language, and the writing was tightened. Still can be found if you know where to look. (I have a German edition cuz I wanted to hear the man say it in his native language-- btw, I am not German).
