89 Enumeration
For TACL, the level-89 enumeration clauses for a field of type ENUM are translated to
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;
