Structure field in EGL source format

An example of a structure field is as follows:
    10 address;
      20 street01 CHAR(20);
      20 street02 CHAR(20);
The syntax diagram for a structure field is as follows:

Syntax diagram for a structure item
level
Integer that indicates the hierarchical position of a structure field.
structureFieldName
Name of a structure field. For rules, see Naming conventions.
*
Indicates that the structure field 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 field.
length
The structure field's length, which is an integer. The value of a memory area that is based on the structure field 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 field value. The mask is present with the data at run time.
dataItemPartName
Specifies the name of a dataItem part that acts as a model of format for the structure field 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 field 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 field is not an array unless you specify otherwise. For details, see Arrays.
property
An field property, as described in Overview of EGL properties and overrides.
