> It's easier to fix your problem by importing the data correctly--it appears that Stata doesn't understand your data structure. Your data are a .txt file, but how are the delimited? (It looks like a tab from your example) What command did you use to import them? You may want to try opening the file up in a spreadsheet program and saving them as a tab-delimited or a comma-delimited file so that you know how to properly specify your import command (e.g., insheet, infile, etc). Also, you could try converting the file to .dta or other filetypes using Stat Transfer. The point is that whatever import command you used did not tell Stata about the correct delimiter and so it placed all the observations into one column (v1). Your data structure looks consistent, so I doubt that one of the import commands just won't work for you, but if not, then try using the -split- command rather than the -substr- function. So with the first observation: ****** clear inp str90 var1 "oilseed farming 100 cotton farming 2000 .1" end split var1 li ***** ~ Eric __ Eric A.
