Abstract

cf2 is a slight variation of cf to list the observations where differences exist. Option verbose must be specified to obtain the listing. Like cf, cf2 compares varlist of the data in memory (master data) to the corresponding variables in filename (using data). cf2 returns 0 if the specified variables are identical and 9 if there are any differences. Only the variable values are compared. Variable labels, Value labels, notes, characteristics, etc. are not compared. In the listings, variable names given for the 'using' dataset are a slight modification of the actual variable names given in the 'master' dataset. 'Using' varnames are truncated to a maximum of 7 characters and then are preceded by an underscore character. This is version 2.1.7 of the software.
