Definition Attributes
FORTRAN Output. The following shows how DDL translates definitions and
descriptions of enumeration clauses into FORTRAN source code:
DDL Type
DEF status TYPE ENUM BEGIN.
89 no-error.
89 read-error.
89 write-error VALUE 3.
END.
DEF old-status TYPE status
DEF cpu.
2 state TYPE ENUM.
89 stop.
89 pause.
89 running.
END.
DEF system-state.
2 cpu0 TYPE cpu.
2 cpu1 TYPE cpu.
END.
