I want a unique series as input and a list (with, for example, three series)
as output, and I want the output series be named in accordance with the
series input.

Yes I think so. I would like something like this could be possible in gretl:
function foo(string name)
series y=@name
#some calculation here
series @name_out=y^2 #for example
return series @name_out
end function
or alternatively, if we had a function to obtain the "external" name of a
variable, for example "sername(y)":
function foo(series y)
string name= sername(y)
series @name_out=y^2 #for example
return series @name_out
end function
