Split Variable Format Data Sets Option
When the ds_options bit DSOPT_split_varfmt_ds (bit value 65536) is set, variable format data sets are treated slightly differently. The record type 0 tables contains the fixed part of all records regardless of their record types. However, the table has exactly the same layout as above. The tables for all the other records only contain the variable part of the records and the keys from the fixed part.
The table named main_type1 in the above example will now contain the key cust_no and the variable part. The SQL statement to create this table is shown as follows:
create table main_type1
