The command `dptest' is a utility for facility test and performance test. Check a database generated by the command or measure the execution time of the command. This command is used in the following format. `name' specifies a database name. `rnum' specifies the number of the records. `bnum' specifies the number of the elements of the bucket array. `pnum' specifies the number of patterns of the keys. `align' specifies the basic size of alignment. `fbpsiz' specifies the size of the free block pool.

Retrieve all records of the database above.
- dptest rcat [-c] name rnum bnum pnum align fbpsiz
Store records with partway duplicated keys using concatenate mode.
- dptest combo name
