>--MERGE--FIELDS=-(logical-expression)--FORMAT=f-----<<

Note: The maximum size of a merge field is 256 characters.

In this COBOL system, the following parameter fields for this control statement are only parsed and ignored:

Parameter	Fields
FIELDS	`(FILSZ=x \| size=y]`

Use the following table as a guide to help you understand the options that are ignored:

Symbol	Meaning
(...)	Options within these brackets are required.
[...]	Options with these brackets are optional.
+	This symbol follows a set of required or optional brackets to indicate that more than one option can be specified, delimited by a comma.
\|	This symbol delimits options enclosed in required or optional brackets, to indicate a choice from these options.

The following options for the logical-expression field are supported:
