1.2 Data files for the Examples
===============================

Many of the examples in this Info file take their input from two sample
data files.  The first, 'mail-list', represents a list of peoples' names
together with their email addresses and information about those people.
The second data file, called 'inventory-shipped', contains information
about monthly shipments.  In both files, each line is considered to be
one "record".

   In 'mail-list', each record contains the name of a person, his/her
phone number, his/her email address, and a code for his/her relationship
with the author of the list.  The columns are aligned using spaces.  An
'A' in the last column means that the person is an acquaintance.  An 'F'
in the last column means that the person is a friend.  An 'R' means that
the person is a relative:

   The data file 'inventory-shipped' represents information about
shipments during the year.  Each record contains the month, the number
of green crates shipped, the number of red boxes shipped, the number of
orange bags shipped, and the number of blue packages shipped,
respectively.  There are 16 entries, covering the 12 months of last year
and the first four months of the current year.  An empty line separates
the data for the two years:
