How to edit input parameters for user-defined/customized SVB node in workspace?

To load a user defined or customized SVB node in workspace, two files are necessarily needed: one is the SVB macro code (.svx file) and the other is the .dmi file which would call the .svx macro and take input information from users through the SVB node UI.

Examples of Statistica existing SVB node functions (.dmi and .svx files) can be found at C:\Program Files\StatSoft\Statistica 13\DataMiner\.
Every SVB node function has two associated files with same name but with two different file extension: .dmi and .svx.  

To define a new SVB node, one can create both .svx and .dmi file and load the .dmi file through "import new node" in workspace node browser to add the new svb node into workspace. 
Refer to this article for more details on how to write custom workspace node (.svx and .dmi files) and how to deploy it to workspace.

How to edit the .dmi parameters for SVB node in workspace?

RESOLUTION 1:

Define input parameters for SVB node through node UI "Edit parameters" dialog.

• Double click on the SVB node, or right click on the SVB node, select "Edit parameters"
• In the "Edit parameters" dialog, there is a tab "Add new parameter..."  at the bottom of the dialog.
• Click on the "Add new parameter" tab, it will allow you to add new parameters to the dmi file of the SVB node. 

RESOLUTION 2:

Locate and edit the .dmi file directly to control the parameters and values shown in the "Edit parameter" dialog in workspace node UI.
