A couple of points. [For reference I am using 1.7.6rc1 dated 27-7-08 on Windows & Linux.] A. I have been trying to upload updated versions of my SFA packages to the gretl server. The packages are created and seem to operate properly on my computer. But the upload generates an error message: "couldn't parse current_fnfiles/sfa_mod.gfn" where sfa_mod.gfn is the package name. I have had the same error under both Windows and Linux. B. The behaviour of the package editor suggests that a sample script is required. Is this correct? As I recall this was not the case in the past, but now the save command generates an error message if there is no sample script. I understand that it may be good practice but should it be a requirement? Also, it would be convenient if the button marked "Edit sample script" could provide the option to load a pre-written script. Finally, going back to the problem that appeared to affect the negation operator. Unfortunately, by the time I read the request to send a copy of the problem script I had edited my script files so much that I cannot recover a version that generated the error. I will see if I can reproduce the problem but it may have been a one off. Gordon
