COLUMNS

THE COLUMN(START-END) or COLUMN(START,WIDTH) sub-descriptor defines the data columns occupied by a data element. The first available column in a GAV data file is one. COLUMN sub-descriptors are only used in GAV schema files of the FIXED category.

The START-END defines an inclusive range, whereas, START,WIDTH defines an initial column and width. For example: COLUMN(1,5) and COLUMN(1-5) are equivalent, and so are COLUMN(10,5) and COLUMN(10-14).

Example:
