To be fair, that is not entirely true. In Pascal, there are three
cases (you can argue that this doesn’t improve anything):
(a) statically allocated arrays where the programmer chooses the
bounds, e.g.
const
InBitData: array [1..4] of Integer = (128, 32, 16, 64);
(b) strings, which start at 1, as historically, the length of the
string was stored at position 0; pascal uses length-delimiting instead
of NUL-delimiting.
(c) dynamically allocated arrays which always start at 0.
So let aside the historical cruft from Strings, Pascal uses zero-based
indexing unless told otherwise.
