DDL Command
Pathmaker Application Definition Language (PMADL)

DDL Command The DDL command invokes a DDL compiler interactively and suspends PMADL until
the DDL process terminates.
?DDL [ command ]
command
Specifies the name of a command line to pass to DDL to use as its start up
command line.
If you do not specify a command line, PMADL passes a DDL DICT command to
open the DDL dictionary embedded in the current Pathmaker catalog.
If the Pathmaker catalog is open for read-only access, a DICTR command is passed
instead. If no Pathmaker catalog is currently open in PMADL, no default
command line is passed to DDL.
Usage Considerations The DDL command must be the last or only command on the command line. PMADL
treats any text on the command line following the keyword DDL as part of the
command line to pass to DDL.
You can use the DDL command only if you are running PMADL interactively. You
cannot use the DDL command from within a PMADL source file.
PMADL invokes DDL from the process configurations in the currently open
Pathmaker catalog. If no catalog is currently open, PMADL uses the version of DDL in
your current system.
Examples The following command starts DDL with the EDIT command:

The following command starts DDL with the DDL DICT command:
