Structure item in EGL source format

An example of a structure item is as follows:

    10 address;
      20 street01 CHAR(20);
      20 street02 CHAR(20);

The syntax diagram for a structure item is as follows:

level

Integer that indicates the hierarchical position of a structure item.

structureItemName

Name of a structure item. For rules, see Naming conventions.

*

Indicates that the structure item describes a filler, which is a memory area whose name is of no importance. An asterisk is not valid in a reference to an area of memory, as noted in References to variables and constants.

primitiveType

The primitive type assigned to the structure item.

length

The structure item's length, which is an integer. The value of a memory area that is based on the structure item includes the specified number of characters or digits.

decimals

For a numeric type (BIN, DECIMAL, NUM, NUMC, or PACF), you may specify decimals, which is an integer that represents the number of places after the decimal point. The maximum number of decimal positions is the smaller of two numbers: 18 or the number of digits declared as length. The decimal point is not stored with the data.

"dateTimeMask"

For items of type INTERVAL or TIMESTAMP, you may specify "dateTimeMask", which assigns a meaning (such as "year digit") to a given position in the item value. The mask is not stored with the data.

dataItemPartName

Specifies the name of a dataItem part that acts as a model of format for the structure item being declared. For details, see typeDef.

embed recordPartName

Specifies the name of a record part and embeds the structure of that record part into the current record. The embedded structure does not add a level of hierarchy to the current record. For details, see typeDef.

recordPartName

Specifies the name of a record part and includes the structure of that record part in the current record. In the absence of the word embed, the record structure is included as a substructure of the structure item being declared. For details, see typeDef.

occurs

The number of elements in an array of structure items. The default is 1, which means that the structure item is not an array unless you specify otherwise. For details, see Arrays.

property

An item property, as described in Overview of EGL properties and overrides.
