Re: [Gretl-users] In loop list modification

In process of learning the gretl programming interface I'm trying to write a stepwise regression procedure (btw, does this exist already?), and encounter strange results when I apply the -= operation to a list within a loop. So outside of a loop when I execute: xlist -= Z2 the Z2 variable is removed from the list xlist. Inside a loop, however, xlist only contains Z2 and not the other variables...
