To manually create a new data dictionary

This section describes how to create a new data dictionary manually. It may be easier to create a new data dictionary by starting with an existing data dictionary created by Campaign.

1.	Create an empty .dat file (length = 0) and a corresponding .dct file.

2.	In the .dct file, define fields in the format:

< Variable_name>, <“ASCII string” or “ASCII Numeric”>, < Length_in_bytes>, < Decimal_point >, < Format>, < Comment>

Use Unknown for the format and leave the comment field blank, as in the following:

acct_id, ASCII string, 15, 0, Unknown,

hsehld_id, ASCII Numeric, 16, 0, Unknown,

occptn_cd, ASCII string, 2, 0, Unknown,

dob, ASCII string, 10, 0, Unknown,

natural_lang, ASCII string, 2, 0, Unknown,

commun_lang, ASCII string, 2, 0, Unknown,

3.	You can now map a new table to a file using this data dictionary.
