I would appreciate a gretl command where the values of all variables in a data set is sorted in ascending or descending order by one of the variables, and one then can save the data set with the new sorted ordering. I know that it is possible to use e.g. anew = sortby(b,a) bnew = sort(b) a = anew b = bnew delete anew bnew to sort in ascending order, but it is tedious when one have many variables. It would be easier with a command e.g. sortallby(b) and dsortallby(b) that sorts the values of all variables at the same time by increasing or decreasing values of some of the variables.
