Abstract

sencode is a sequential version of encode. It takes, as input, a string variable, and generates, as output, a numeric variable, with value labels corresponding to values of the string variable. Unlike encode, sencode orders the numeric values corresponding to string values in the sequential order of appearance in the input string variable in the data set, or in another order specified by the user, instead of ordering them in alphanumeric order of the string value, as encode does. The mapping from numeric code values to string labels may be one-to-one (coded in order of first appearance of the string value) or many-to-one (coded in each observation by the position of that observation in the data set, or in the user-specified ordering).
