The data set RADIO contains data from a survey of 336
listeners. The data set contains information about listeners and their preferences
in radio programming. The INFILE statement specifies the external file that
contains the data. MISSOVER prevents the input pointer from going to the next
record if it doesn't find values in the current line for all variables listed
in the INPUT statement. Each raw-data record contains two lines of information
about each listener. The INPUT statement reads only the information that this
example needs. The / line control skips the first line of information in each
record. The rest of the INPUT statement reads Time1-Time7 from the beginning
of the second line. These variables represent the listener's radio programming
preference for each of seven time periods on weekdays (see
Completed Survey Form ).
Listener=_N_ assigns a unique identifier to each listener.
