Is it possible mawk does not use zero-based indices?
ie:
mawk substr(x, 1, 1)
gawk substr(x, 0, 1)
Should return the same thing
from man awk:
" Finally, here is how mawk handles exceptional cases not discussed in
the AWK book or the Posix draft. It is unsafe to assume consistency
across awks and safe to skip to the next section.
substr(s, i, n) returns the characters of s in the intersection
of the closed interval [1, length(s)] and the half-open interval
[i, i+n). When this intersection is empty, the empty string is
returned; so substr("ABC", 1, 0) = "" and substr("ABC", -4, 6) =
"A".
