I think that negative indeces maybe a useful feature, because a few languages have this already (notably MUMPS AFAIK). The main difficulty for the such implementation in "C" or derived languages is the method of calculating "effective address". IMHO the PHP has not such limitations, because it has got dynamically allocated cells in arrays (I can note big convergence both PHP and MUMPS in this issue). -- WBR, Yury Bokhoncovich, SysAdmin at FIS.
