89 Enumeration Clause
•
For COBOL85, the level 89 enumeration clauses for a field of type ENUM are
translated into level 88 items. These items follow the source code for the ENUM
field, a NATIVE-2 clause.
•
For FORTRAN, the level 89 enumeration clauses for a field of type ENUM are
translated into comments. These comments follow the source code for the ENUM
field, an INTEGER*2 type declaration.
•
For Pascal, the level 89 enumeration clauses for a field of type ENUM are
translated into constants. These constants precede the type declaration for the
definition or record within the same section.
•
For pTAL or TAL, the level 89 enumeration clauses for a field of type ENUM are
translated into LITERALs. If the type of a single-field definition is ENUM, and you
do not specify NOTALALLOCATE, DDL generates LITERALs followed by an INT
for the definition; for example:
LITERAL ENUMERATION-NAME1 = ENUMERATION-VALUE1,
ENUMERATION-NAME2 = ENUMERATION-VALUE2,
... ;
INT DEF-NAME;
If the type of a field in a group definition is ENUM, DDL generates LITERALs
followed by a STRUCT template.
•
For TACL, the level 89 enumeration clauses for a field of type ENUM are translated
into ?SECTION directives of type TEXT followed by an ENUM for the item with
which the level 89 clauses are associated:
?Section ENUMERATION-NAME1 Text
ENUMERATION-VALUE1
?Section ENUMERATION-NAME2 Text
ENUMERATION-VALUE2
...
?Section DEF-NAME Struct
Begin
ENUM DEF-NAME;
End;
Enumeration Clause Examples
The following examples show DDL enumeration clauses and the source code that DDL
generates for these clauses in different languages.
