DDL Compiler Commands

TAL
The DDL compiler performs all of the syntax checks listed under the TALCHECK
command before writing the pTAL or TAL source output. If the DDL compiler finds a
syntax error, it does not write the source output for the object with the error; it does
write source output for an object if only a warning is issued.
The lower bound for pTAL or TAL arrays can be set with the TALBOUND command.
In Example 9-54 on page 9-107, the DDL compiler opens the dictionary, opens and
then clears the file \DALLAS.$DATA.SALES.TALSRC, retrieves the record
CUSTOMER from the open dictionary, translates it to pTAL or TAL source code, and
then writes it to the open pTAL or TAL source code file. For the definition of the
CUSTOMER record, see the sample database schema in Appendix B, Sample
Schemas.
