Code: Select all

Sorting data from earliest to oldest

Hi all,
I have a excel file which sorting from earliest to oldest. So it's unconventional for me to copy and paste it to eviews (I usually resort in excel then copy to eviews, but this way takes me a lot of time). I want to know the code in eviews to fix this problem. Thanks a lot :)
