Step 4. Create a Subfiles Definition Member in Parmlib

To create the FDS, first define its subfile characteristics to CA Disk. A sample set of subfile definition entries is supplied in the parameter library. The only variable in each entry is the number of records (capacity) you expect to need in each subfile. The minimum is one. For initial use, the supplied capacities should be more than sufficient, and provides the best performance. Copy the sample definitions (member FDSAMPLE in parmlib) into a new member of parmlib named FILEDEFN. This new member is used to initialize your FDS.
