Well, my experience matches Johnny's. I used many derivatives of
MicroSoft BASIC - PET, Apple INTBASIC, Applesoft, Exidy Sorcerer, and

original 1960s Dartmouth BASIC (for which I have a copy of the manual)
also started at 0 (cf. page 38); indeed if you didn't explicitly DIM an
array, you got eleven elements indexed 0...10.
I wrote a lot of BBC BASIC. DIM(9) allocates ten elements, 0..9,

FORTRAN, yes. BASIC (which dialect might we be
talking about?) normally
actually start with 0. However, BASIC is weird, in that
the DIM
statement is
actually specifying the highest usable index, and not the size of the
array.
Eh? Not in any BASIC I ever used. They all started at 1. Can't vouch
for the later Microsoft "visual" variants but the original 1970's era
BASIC
started with 1.
DIM X(10) gave you ten elements from 1...10
