Building DDL Input Pressing F2 builds the data definitions and runs the DDL compiler. To build input for
DDL, Data Build uses the Source Record Descriptions files, RECDEF01, RECDEF02,
and RECDEF03, and builds a DDL input file for each from the record definitions that
describes the data.
The DDL statements and commands in the DDL input files are passed as input to the
DDL compiler. The compiler translates these into an internal data definition format.
DDL takes the compiled object definitions from the dictionary, translates the
definitions from the dictionary, and writes the definitions to the output files,
COBDEFS and FUPDEFS.
To build input for DDL and generate DDL output, do the following:
1. Press F2 at the Main Menu.
Data Build displays information on your terminal showing the starting and
stopping time stamps. The display information is simultaneously logged to the
spooler.
2. Press any key to return to the Main Menu. At the bottom of the Main Menu, this
message is displayed:
BUILD Complete — CHECK DDL RESULTS ON SPOOLER.
3. To check the results on the spooler, press F12 to run Peruse.
4. Check spooler locations #BLDDDL and #DDL. Make sure you check the last page
of #DDL for any errors or warnings. Correct any errors or warnings before going
to the next step.
5. Exit Peruse and return to Data Build.
