16:04 CoCoALib Feature #312: LongRange(a,b) returning vector of long a..b (included)

12:35 CoCoALib Feature #312 (Closed): LongRange(a,b) returning vector of long a..b (included)

In fact it is particularly useful for calling *submat*.
So I s... -

And *NegativeValue* instead of *NotNonNegative*? -
