│ THE INPUT FILE: A DBase (DBF) file containing a list of computer experts. │
│ │
│ WHAT WE WANT: We will output the file's data in columnar format, with an │
│ appropriate heading at the top of each column. We want │
│ the contact's name, his voice number, and his fax number. │
│ │
│ HOW WE DO IT: When in DBF mode, there is no $FLINE. Rather, each record │
│ is pre-parsed into fields. This makes our job very easy. │
│ We do, however, have to check the DELETED field: if it is │
│ set to "Y", the field has been deleted from the database, │
│ although it has not yet been replaced or removed. We will │
│ skip any addresses from "Faster Publishing Ltd", using the │
│ IGNORE command. We will use the TRACE command to generate │
│ a trace file that lets us watch the IGNOREs take effect. │
