C Command
•
Write the C source statements to the C source file.
C
opens the specified C source file, translates all subsequent DDL objects defined by
statements or specified in OUTPUT statements into C source statements, and
writes the source statements to the open C source file. If a C source file is already
open, this command closes the current file and opens a new source file.
c-source-file
identifies the C source file. If c-source-file is omitted, DDL lists the C source
statements at the home terminal.
!
purges the contents of any existing C source file before opening the file. If the
specified file does not exist, DDL ignores the exclamation point.
NOC
closes the currently open C source file and stops translating subsequent DDL
objects. NOC is the default.
C Command Guidelines
The following points are guidelines for using the C command:
•
The specified C source file must be an EDIT file, an unstructured file, or a
sequential device such as a terminal, a spooler, or a process. If the file exists but is
not one of these types, DDL issues an error message and does not open the file.
•
Only one C source file can be open at a time. If you use the C command when you
already have a C source file open, DDL closes the current source file before
opening the new source file.
•
If the C source file already exists and the exclamation point is omitted, DDL
appends the DDL objects to the end of the file’s original contents. DDL does not
replace any existing objects.
•
The compiler can translate DDL objects specified in an OUTPUT statement only if
the dictionary containing these objects is open.
•
Each DDL object translated into C source code is written to the C source file in a
separate section that has the same name as the DDL object it contains. To
suppress the generation of individual section headings with the SETSECTION
command.
