Why do you want to do that? Series names or named lists should typically be all you need. (in theory)

Series names or named lists should typically be all you need. (in theory) It's tough to explain, but in short: we have database with houndrets of series retrived from dbnomics, but after downloading we need to tune some of them (interpolation, filtering and so on). We want to have a tunned series next the original one, but all tunning staff we want to run *after* downloading the whole database. So, setting variable ID via script would help us. I see -- I guess I would recommend to use additional datafile files ('store' command) and/or database files to group the related variables together. If in the end you want to have them all in one file, read them into a fresh file in the wanted order. cheers sven _______________________________________________ Gretl-users mailing list -- gretl-users(a)gretlml.univpm.it To unsubscribe send an email to gretl-users-leave(a)gretlml.univpm.it Website: https://gretlml.univpm.it/postorius/lists/gretl-users.gretlml.univpm.it/

There's no command or function that specifically targets this operation, but it's fairly simple to re-order the series in a dataset via lists -- which can be treated as vectors (of series ID numbers) for manipulation -- plus the "store" and "open" commands. Here's an example. Suppose we want to move the COLLEGE series from ID 9 to ID 2 in Ramanathan dataset 4-10: <hansl> open data4-10 list L = dataset newpos = 2 oldpos = varnum(COLLEGE) matrix mL = L tmp = mL[newpos] mL[newpos] = oldpos mL[oldpos] = tmp L = mL store reordered.gdt L open reordered.gdt </hansl> Allin _______________________________________________ Gretl-users mailing list -- gretl-users(a)gretlml.univpm.it To unsubscribe send an email to gretl-users-leave(a)gretlml.univpm.it Website: https://gretlml.univpm.it/postorius/lists/gretl-users.gretlml.univpm.it/

Ha, we all forgot about the simplest method: dataset renumber <varname> <id>
