I run gretl 2019d for windows 64bit. In previous versions the order of opening an (existing) .inp file and a (existing) .gretl file did not matter. One could open first a .gretl file, then open a .inp file, choose "No" to the question "Start a new gretl instance?" and the two would be linked and the script in the .inp file could draw data from the .gretl file immediately, without the script in the .inp file containing a command to that effect. But also, one could start by opening first the .inp file, etc. and things worked the same way. Not in the 2019d version though. Here it appears it only works if one opens first the .inp file and then the .gretl file, but not the other way around. Again, I am not referring to the case where one has opened a .gretl file, and then creates a new .inp file and writes a script. The issue appears only when a .inp file already exists with a script in it. -- Alecos Papadopoulos PhD Athens University of Economics and Business web: alecospapadopoulos.wordpress.com/ skype:alecos.papadopoulos
