Ok, but in that example "endogenous" is a list, so this implies that the user 
should define it first:

list endogenous = income
list components = decomp(endogenous)

and I think that, given that my function does not need more than one input 
variable, gretl should have a way to obtain the same effect with only one 
line:

list components = decomp(income)

May be the function "varname()" of the "sprintf" command can help in doing 
something like that?
