This topic gives rules and examples for filling in positions 1 through 44 of the data description specifications (DDS) form. DDS keyword entries for ICF files (positions 45 through 80) gives rules and examples for specifying DDS keywords.
For more information about keywords for ICF files, see the ICF Programming
book.
Specify the entries in the following order to define an ICF file:
Repeat the record-level entries and field-level entries for each record format in the file.
Specify at least one record format in the file.
The maximum number of record formats in an ICF file is 1024. The maximum number of fields in any one record format is 32 767.
You can find an explanation of file level, record level, and field level as well as the syntax rules for specifying DDS keywords in the DDS Reference: Concepts information. You can also find a complete ICF example in the DDS Reference: Concepts information.
The following figure shows an ICF file coding example.
