Identifier-4 cannot be defined as a floating-point item.
Identifier-4 can be a DBCS or national data-item. 
Identifier-5 can be a DBCS or national
data-item. 
The DELIMITER IN phrase can be specified only if
the DELIMITED BY phrase is specified.
The identifiers must not be
defined as alphanumeric edited or numeric edited items.
If no delimiter is found in identifier-1, then identifier-5 is space filled. 
If identifier-5 is a national item, it is padded or filled as needed with the 'national to national' padding character specified in the NTLPADCHAR compiler or PROCESS statement option.
When identifier-1
(the sending field) is a DBCS or national data item, identifier-6
indicates the number of characters (not the number of bytes) examined
in the sending field. 
The COUNT IN phrase must not be specified unless the DELIMITED BY phrase is specified.
