This topic gives an example of a Field Definition File that describes the fixed formatted file.

field1 1 12 13
field2 14 24 0
field3 25 55 56
field4 78 89 90
field5 100 109 0
field6 110 119 120
field7 121 221 0
*END
The following is a brief explanation of the
Field Definition File format:
- = Comment line
*END = End of definition, this must be included
Field Starting Ending Null
Name Position Position Character Position
_________________________________________________________
field1 1 12 13
field2 14 24 None
field3 25 55 56
field4 78 89 90
field5 100 109 None
field6 110 119 120
field7 121 221 None
- Field Name
- This name is the name of the to-file field name.
- Starting Position
- This is the starting position for the field in the import file of each record. This is the byte position.
- Ending Position
- This is the ending position for the field in the import file of each record. This is the byte position.
- Null Character Position
- This is the position for the NULL value for the field in the import file
of each record. The value zero specifies that NULL does not have a value.
The value in the import file can be 'Y' or 'N'.
'Y' means the field is NULL. 'N' means the field is not NULL.
Each column must be separated by a blank character.
Each row must be sequentially ordered.
An alternative for creating the Field
Definition File is using the *COL keyword instead of the actual column names.
*COL indicates the positions of the data in the stream file for all the columns
in the target files listed in order. The following example shows how to describe
fixed formatted files using the *COL keyword:*COL 1 12 13 *COL 14 24 0 *COL 25 55 56 *COL 78 89 90 *COL 100 109 0 *COL 110 119 120 *COL 121 221 0 *END
