This chapter describes the initialization statements (which make up an initialization stream) that you must put into the data set you allocated in Step 1. Allocate a Data Set for the BDT Initialization Stream. The initialization stream is run when the operator starts BDT. It initializes the BDT address space. This chapter describes:

• The number of initialization streams you should have.
• The IBM-supplied initialization streams in SYS1.SBDTSAMP.
• The rules for coding initialization statements.
• The format of each initialization statement. The statements are presented in alphabetic order (for easy reference), not in the order in which they must appear in the initialization stream. (Rules for coding initialization statements shows the required order.)
• Initialization statement parameters that the operator can override.
