4D 2004 supports CLI (Command Line Interface) for Mac OS X. Here is an example of how to launch a 4D database structure with a data file.
Using the terminal in Mac Os X, use the following syntax.
Syntax: Path/ApplicationName -d DataPath StructurePath
4th\ Dimension.app/Contents/MacOS/4th\ Dimension -d/Users/Roger/Bases/MyBase/MyBase.4DD /Users/Roger/Bases/My-Base/MyBase.4DB
No dialog boxes appear and now you are ready to work on your database.
