Under the header ITEM STRING LIST, BPSIA prints out a table showing the differences between the subschema format and schema format of a record type.
An “Item String“ is a series of items defined in the subschema format of the record type in the same contiguous order as those in the schema format. If the subschema format is exactly the same as the schema format, the subschema record is an item string.
Example

The table contains the following entries:
REC REF
Number of the record type
RECORD-NAME
Name of the record type
COMPL REC
Marker for identical subschema and schema record:
*: Identical
USER-REC DISPL
Displacement of an item string in the subschema record relative to the beginning of record (in descending order of displacement)
DB-REC DISPL
Displacement of the item string relative to the beginning of the schema record including the set connection data
LENGTH
Length of the item string in the subschema record
V: preceding the length indicates that the item in question is a variable item
The entries from USER-REC DISPL to LENGTH are repeated for each item string in the subschema record.
