Declaring a Structure Body
The syntax for a structure body is either a BEGIN ... END construct or a LIKE
construct:
{BEGIN declaration [ declaration ... ] END}
{LIKE structure-identifier;}
declaration
is the declaration of a STRUCT item: a simple data item declaration, an array data
item declaration, a substructure declaration, or a FILLER declaration. These types
of declarations are described later.
LIKE structure-identifier
specifies that the definition of a structure or substructure is to be identical to that of
an existing structure or substructure. structure-identifier is the name of an
existing variable of type STRUCT.
