Syntax Generator Input

Input to the syntax generator consists of the following control blocks created by the CA-supplied macros:

• Database definition (DBD) control blocks—Define the segment types, the physical hierarchical structure, and other characteristics of each database for which a view is defined in the PSB. The DBD control blocks are used to produce the CA IDMS/DB schema, DMCL, and subschema source statements.
• Program specification block (PSB)—Defines the views of all physical and/or logical databases available to a DL/I application that uses the PSB. The PSB control block is used to produce the IPSB source statements.
