This is fixed in the forthcoming GP 2.4.2 I recorded it as bug #686. > > k=1;vector(6,i,[k*1,k=k*10%7]) > %2 = [1, 3, 2, 6, 4, 5] > > I think this is a nice way if you don't want the result from the last expression(?) > Only 2. example works as expected, but is the method safe? Actually yes, but you could just do k=1;vector(6,i,l=k;k=k*10%7;l) which is safe. > Now 2 suggestions: > > > vector(6,i,1) > %3 = [1, 1, 1, 1, 1, 1] > > I think it would be nice to be allowed to exclude unused locals in vector and matrix.

What we need is standardised way to write and publish library of GP functions. Would you like to try ? Cheers, Bill.
