Hi Ralph,

$(user.home) is a java system property, so you can also use other system property such as $(user.dir), but there is no default system property for workspace. I think you can add such a system property from BOY script:

	importPackage(Packages.org.csstudio.opibuilder.scriptUtil);
	importPackage(Packages.java.lang);
	var s = FileUtil.workspacePathToSysPath("/BOY Examples"); // replace "/BOY Examples" to your relative path in workspace.
	System.setProperty("user.workspace", s);

You can attach this script to the display file and trigger it with a constant PV such as 0 so it can be executed once the display starts up. Then you can use $(user.workspace) as command directory.

Hope it works for you,
Xihui
