I take it that both matchvars are string variables. Otherwise there would be no problem at all as the difference would be just in the formatting. If, as you suggest, in dataset 1 there is always a zero first, its more efficient to get rid of that one. This implies creating a str5 variable using the string finction substr(matchvar1,2,5). See -help substr-Hi I am trying to merge two datasets which have the same variable coded differently in each. In dataset 1, the variable is 6 digits, with the first digit being a zero. in dataset 2, the same variable is 5 digits, and the first digit (which should be a zero) as been truncated. Does anyone know how to add a zero to the variable in the second dataset?
