Hi, this will not work in case when one of the variables does not contain all codes present in all other variables. (table shows unique values only,sorted alphabetically, like Stata does it) Var1 Var2 Var3 A B A B C B C After encoding Var1 will be coded as 1=A, 2=B, 3=C; Var2: 1=B, 2=C; Var3: 1=A,2=B, which is in all probability not what moleps islon wanted. In general one must find a union of all possible values, then encode. Practically this is probably easier to solve by reshaping the data to the long format, encoding the single string variable, and then reshaping back. If there are a few values to label, and those are known a priori, I would hardwire them into the program and label manually.

Is there an easy way to encode all 30 variables using the same label or do I have to do it manually. Also is it possible, somehow, to specify stata to start encoding with tha value 0 instead of 1 ?
