Use these positions to specify record format names and field names.
Names must begin in position 19.
When you specify an R in position 17, the name specified in positions 19 through 28 is a record format name. You can specify more than one record format for an ICF file, but each record format name must be unique within that file.
When you specify a blank in position 17, the name specified in positions 19 through 28 is a field name. Field names must be unique within the record format. For ICF files, the order in which field names are specified in the DDS is the order the fields take in the input and output buffers.
The keywords CANCEL, EOS, FAIL, and RQSWRT must have option indicators when they apply to a record with fields. Fields are ignored at run time (not sent across the line) when any of these keywords are in effect. At creation time, if any of these keywords have no option indicator and apply to a record with fields, a severe error is issued and the file will not be created.
