It may be obvious, but awk(1) uses 1-indexing for arrays and string
offsets, and shell arguments are indexed from 1 too (which may be
reasonable given the special behavior of argv[0], but I think this
resulted in rc(1) being 1-indexed for lists). pic(1) sensibly uses
1-indexing in the "Nth" notation.
I never thought of it like that wrt awk. However, I always thought of $0 as
"self" in higher level OO languages.
On the other hand, before C, both B and BCPL used
zero-based indexing.
So if we trace C's family tree, there is certainly precedence for
zero-based indexing into arrays.
Ah. OK. I never used either language. I get the impression that BCPL
wasn't used / known much in the US, but I could be wrong. I was exposed
to BASIC and FORTRAN (and computer programming) circa 1976 and to C
in 1980. Anything before then is before my time ... :-)
