Generating Source Code

The DDL compiler can generate source code for definitions and records in any of the

languages DDL supports: C, COBOL, FORTRAN, Pascal (on D-series systems), pTAL,

TACL, or TAL. In addition, the DDL compiler can generate source code for constants

and SPI token types, token codes, and token maps in C, COBOL, Pascal (on D-series

systems), pTAL, TACL, or TAL. The DDL objects, once translated to source code, are

used for a variety of application functions. DDL objects can describe the data in a

database and the data local to an application; messages used for interprocess

communication; units of work for the Transfer Delivery System (only on G-series

systems); and SPI tokens used to build SPI messages.

For the DDL compiler to generate source code, the appropriate language source code

file must be open. To open a language source code file, you can include one or more
