Don't use long as the name of the variable that you're using. Long is a variable type, so STATA is looking for a valid variable name. . gen long=length( district_name) too few variables specified r(102); . gen str long=length( district_name) too few variables specified r(102); . gen xxyy=length( district_name) . tab xxyy xxyy | Freq.

Gamas Sent: Monday, October 25, 2004 4:48 PM To: statalist@hsphsun2.harvard.edu Subject: st: length(s) question Dear all, I am trying to determine the length of a string variable because this length changes in each observation and I want to work with substr, so I need the variable to be the same size accross observations. But I'm getting an error message that I simply don't understand how to fix. I write: generate long = length (vp40_11), vp40_11 is the string varible whose length I want. Error message reads: "too few variables specification","r(102)" However, the help section says to write "generate varname = exp" and exp in this case is length (s), where "s" is the string variable. So I can't really understand which variable is missing. Can anybody help me out? Thanks, Julia Julia A.
