DDS syntax for an ICF file



Syntax for an ICF File. An illustration of a DDS coding form that describes an ICF file.

(1)
Comments (optional): Comments can appear on any line in DDS. They are identified by an asterisk in position 7.

(2)
File level (optional): File-level keywords appear before the first record format name (RECORDA on line 00040).

(3)
Record level (at least one required): R in position 17 identifies RECORDA as a record format name. The record level continues until the first field is specified.

(4)
Field level (optional): ICF file fields must have at least a name (as in FIELDA) and a length. Other attributes can be specified explicitly or by default.

Notes:

  1. Items (3) and (4) can be repeated to specify new record formats within the ICF file.
