Hi, in the function package GUI it is possible to type a matrix literal directly into the corresponding field. In contrast I just found out that with lists this isn't possible, the error from the parser is "expected ) but found SERIES" or sth. like that. BTW, what works is to type in directly an expression with deflist(). I think this proves that having an anonymous list is not the problem. I think it would be useful if typing 'S1 S2 S3' could be understood as deflist(S1,S2,S3), basically just like the plain list syntax works in gretl in other contexts. thanks, sven
