If that's true, it is a black mark against the usually almost obsessive
attention SI pays to 'backward compatability' - to the extent that I wonder
whether it is an unintentional bug.  They have, for a long time,
discouraged the use of implicitly-dimensioned arrays (which, if I reacall,
are neded for DO OVER), but there is probably still plenty of code out
their which uses it.  Is it just DO OVER that has gone, or has the whole
concept of implicitly-dimensioned arrays gone?  ... and what happens when
one does try to use DO OIVER? - is it just regarded as a 'syntax error'?

Regards,


John
