'-RELATIVE----'
- CONSECUTIVE
- Specifies that the file is associated with a consecutive data
set. A consecutive file may be either a native data set or a workstation
VSAM sequential, direct, or keyed data set.
- INDEXED
- Specifies that the file is associated with an indexed data
set. INDEXED specifies that the data set contains records arranged
in a logical sequence, according to keys embedded in each record.
Logical records are arranged in the data set in ascending key sequence
according to the ASCII collating sequence. An indexed file is a
workstation VSAM keyed data set.
- RELATIVE
- Specifies that the file is associated with a relative data
set. RELATIVE specifies that the data set contains records that
do not have recorded keys. A relative file is a workstation VSAM
direct data set. Relative keys range from 1 to nnnn.
