Using the VALUE Clause

Use the VALUE clause to assign values from host variables into fields of a system-descriptor area. You can assign values for items for which you are providing a description (such as parameters in a WHERE clause), or you can modify values for items after you use a DESCRIBE statement to fill the fields for an UPDATE or INSERT statement.

Item Descriptor

Use the Item Descriptor portion of the SET DESCRIPTOR statement to set value for an individual field in a system-descriptor area.
