Such strings have a maximum of 8 characters (as with variable names, longer strings will be truncated). A column of this sort should be headed with the string obs or date, or the rst row entry may be left blank. For dates to be recognized as such, the date strings must adhere to one or other of a set of specic formats, as follows. For annual data: 4-digit years. For quarterly data: a 4-digit year, followed by a separator (either a period, a colon, or the letter Q), followed by a 1-digit quarter. Examples: 1997.1, 2002:3, 1947Q1. For monthly data: a 4-digit year, followed by a period or a colon, followed by a two-digit month. Examples: 1997.01, 2002:10. " So although I haven't tried it, I would use a plain text file (preferably ASCII) with one such short string per line, in the order of the observations in the dataset of course. good luck, sven
