Is it even a 1980s programming language without a Hanoi example?
Here's the program in its all-caps, weirdly indented beauty:
DEFINE('HANOI(N,NS,ND,NI)') :(HANOI.END)
HANOI EQ(N,O) :S(RETURN)
HANOI(N - 1,NS,NI,ND)
OUTPUT 'MOVE DISC ' N ' FROM ' NS ' TO ' ND
HANOI(N - 1,NI,ND,NS) :(RETURN)
HANOI.END
TEST HANOI (5,'A','C','B')
END

In the 1960s, most programming was done on punched cards, and keypunch machines (and many computers) didn't have lower case letters on them. Hence, languages from that era, like FORTRAN, COBOL, PL/I, LISP and assembly language, were written in all-caps. [1] https://en.wikipedia.org/wiki/SNOBOL https://en.wikipedia.org/wiki/SNOBOL
