OCCURS Specifies a subscripted array of like fields or like groups.
OCCURS
DEPENDING ON
Specifies a variable-length array of like fields or like groups. This
clause is for COBOL and DDL source code only.
PIC[TURE] Specifies the data type and size of a field using COBOL notation.
REDEFINES Assigns a new name and, optionally, a new structure to a previously
defined data-storage area.

TYPE def-name Specifies the type and size of a field by TYPE * referring to a previous
definition.
UPSHIFT Specifies that ASCII characters entered in the current field must be
upshifted. Requesters generated by the Pathmaker product upshift
character strings entered into this field; user-written programs must
be coded to upshift them.
USAGE Specifies computational storage allocation for a numeric group or
field.
[NO]VALUE Assigns an initial value to a field or group, or suppresses any initial
value. This clause is for COBOL and DDL source code only.
66 RENAMES Renames a previously defined field or group or set of fields or groups.
DDL ignores this clause when generating FORTRAN, TACL, and
Pascal source code.
88 condition-name Specifies one or more condition names and assigns each to a value
or range of values. DDL ignores this clause when generating
FORTRAN, pTAL,
TACL, TAL, C, and Pascal source code.
89 enumeration Associates a name with a specified or default enumeration value and,
optionally, specifies a display string for the value.
