How to execute command line in the MacOS X Terminal:

To be able to execute most 4th Dimension commands using the MacOS X Terminal, you must first access the folder where the application is found--inside the package (Contents/MacOS path). If the 4th Dimension package is located in the MyDoc folder, then your command line should look like:

 /MyDoc/4th\Dimension.app/Contents/MacOS/4th\Dimension.

You can also execute the command as a background task in a seperate process by passing the "&" character at the end of the command. For example:

 //MyDoc/4th\ Dimension.app/Contents/MacOS/4th\ Dimension &

Note:
The syntax is: path/Application Name
