Use this field-level keyword for named, output-only fields (but not message or program-to-system fields) that are defined so that they overflow onto subsequent display lines.
The keyword causes folding to occur at a blank in the data rather than at the end of the display line. It is used to make long text fields easier to read. The default is for the data to be folded at the end of the physical line.
This keyword has no parameters.
When BLKFOLD is used, the field length is not increased. Therefore, it is possible for a portion of the output data to be truncated.
You cannot specify the BLKFOLD keyword on a floating-point field (F in position 35).
Option indicators are not valid for this keyword.
The following example shows how to specify the BLKFOLD keyword.
