Positions 64 through 68 specify the length of the result field. This entry is optional, but can be used to define a numeric or character field not defined elsewhere in the program. These definitions of the field entries are allowed if the result field contains a field name. Other data types must be defined on the definition specification or on the calculation specification using the *LIKE DEFINE operation.
The entry specifies the number of positions to be reserved for the result field. The entry must be right-adjusted. The unpacked length (number of digits) must be specified for numeric fields.
If the result field is defined elsewhere in the program, no entry is required for the length. However, if the length is specified, and if the result field is defined elsewhere, the length must be the same as the previously defined length.
