[Gretl-devel] array indexing

I recently made some changes so that array indexing in the 
context of the "restrict" command starts at 1 in all cases 
(previously there was a mixture of 0-base and 1-base).

Working again with matrices lately, I recall that gretl matrices
also use 1-based indexation.  So we're consistent.

But is this "right"?  Would we be better to standardize on 
0-based indexing in all cases?  My initial thought was that 
1-base is more intuitive for the "punters", but I have to say it 
seems odd for matrices. Ox uses 0-base; does R do that too?

Allin.
