DDL Compiler Commands

TACL Command

The TACL command instructs the DDL compiler to:
Create and open a TACL source file or open an existing TACL source file.
Translate all subsequent statements that define DDL objects into TACL source
statements.
Translate any DDL objects specified in subsequent OUTPUT statements into TACL
source statements.
Write the TACL source statements to the TACL source file.
{ TACL [ tacl-source-file [ ! ] | NOTACL }
TACL
opens the specified TACL source file, translates all subsequent DDL objects
defined by statements or output from the dictionary into TACL source statements,
and writes them to the open TACL source file. If a TACL source file is already
open, the command closes the current file and opens a new source file.
tacl-source-file
identifies the TACL source file. If tacl-source-file is omitted, DDL lists the
TACL source code at its home terminal.
!
purges the contents of an existing TACL source file before opening the file. If the
specified file does not exist, DDL ignores the exclamation point.
NOTACL
closes the currently open TACL source file and stops translating subsequent DDL
objects. NOTACL is the default.
TACL Command Guidelines
The following points are guidelines for using the TACL command:
The specified TACL 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 TACL source file can be open at a time. If you use the TACL command
when you already have a TACL source file open, DDL closes the current source
file before opening the new source file.
