About This Manual
This manual describes the Data Definition Language (DDL), an HP product for defining
data objects and for translating object definitions to source code for programming
languages and for other products on HP NonStop™ systems.
DDL data objects include:
•
Constants
•
Field definitions
•
Group definitions
•
Records
•
Subsystem Programmatic Interface (SPI) token codes
•
SPI token maps
•
SPI token types
The DDL compiler can translate an object definition to source code for one or more of
these HP products:
•
HP C for NonStop Systems
•
HP COBOL for NonStop Systems
•
HP FORTRAN for NonStop Systems
•
HP NonStop NET/MASTER Network Control Language (NCL)
•
HP Pascal for NonStop Systems (D-series systems only)
•
HP Portable Transaction Application Language (pTAL)
•
HP Tandem Advanced Command Language (TACL)
•
HP Transaction Application Language (TAL)
•
File Utility Program (FUP)
In addition, the DDL compiler can generate its own source code from object definitions
in a dictionary and produce reports on the contents of a dictionary.
This manual gives:
•
An overview of DDL
•
Instructions for using the DDL compiler
•
Syntax descriptions, usage guidelines, and examples for all DDL statements and
commands
