[Gretl-users] about arrays as argument of yahoo_get

Dear all I spent some time before i realized the position of a declaration of array as argument of a function seems to be very critical. I mean that this following script is NOT working "as is", but if i change the position of the declaration it works. ----------------------------------------------------- #ARRAY DECLARATION far from yahoo_get strings P = defarray("A2A.MI", "ANIM.MI") # OPEN SET 10 DAYS nulldata 10 # TIME SERIES  setobs 5 2016-07-01 --time-series # CALL yahoo_get include yahoo_get.gfn ######## QUESTION ITEM ######## strings P = defarray("A2A.MI", "ANIM.MI") #DOWNLOAD LOOP loop i=1..nelem(P)      A=yahoo_full(P[i]) endloop ------------------------------------------------------------ you easily can verify the script isn't working                            BUT if I put the array declaration near the yahoo_get the script works. ----------------------------------------------------- ######## cut off the previous declaration ######## strings P = defarray("A2A.MI", "ANIM.MI") # OPEN SET 10 DAYS nulldata 10 # TIME SERIES setobs 5 2016-07-01 --time-series # CALL yahoo_get include yahoo_get.gfn #ARRAY DECLARATION near yahoo_get strings P = defarray("A2A.MI", "ANIM.MI") loop i=1..nelem(P)      A=yahoo_full(P[i]) endloop ------------------------------------------------------------ now it works. So maybe it's a trivial subjetc but i will appreciate some help to understand why it happens. Cheers Guido
