Syncing Source Code

When you start working on a project that resides on an OpenVMS machine, you need to download source files to your local machine. For this,

  1. Change the downloadNewFiles option to "overwrite" or "edit"
  2. Run "VMS-IDE: Synchronize project files with VMS" command
  3. After all project files are downloaded, change the downloadNewFiles option to "skip" or "edit" to prevent silent overwriting of local files.

Managing Project Source Files

You can view and edit all project files from the Explorer view of Visual Studio Code.

Managing the Project

You can manage your VMS project from the Project Explorer view. To open the view, click Project Explorer icon on the Activity Bar

Managing Dependencies

Use the Project Dependencies panel to manage project dependencies. Assuming that you want to add "Project B" to "Project A" dependencies,

  1. Select "Project A" in the Project Dependencies panel
  2. Right-click "Project B", and select "Add in dependencies to selected" item from the context menu.


To build a project in VMS IDE:

  1. Open the Project Explorer view.
  2. Select the project you want to build in the Project Dependencies panel.
  3. In the Project Description panel, select the required build type (DEBUG or RELEASE) simply by clicking the buildType parameter.
  4. Right-click the project and select Build with dependencies from the context menu.

To build a project using a custom build procedure, edit the task.json file

  "type": "task2cmd",
  "command": "vmssoftware.synchronizer.buildProject",
  "extension": "vmssoftware.synchronizer",
  "parameter": "time.com",
  "label": "VMS: Time",
  "problemMatcher": []


  • parameter is the name of your build procedure (COM file)
  • label meaningful task name

All other parameters must be as shown in example.



To debug your application, press F5. If there is no "launch.json" file in the project directory, you will be asked to select environment. Select VMS Debugger from the popup list.

The "launch.json" file will be created and filled with the required information. There are two types of launch - DEBUG and RUN. For the "program" field, specify the relative path to the executable (from home directory), for example "[.project.bin.release]hello.exe". If the field is empty, VMS IDE will try to fill it with data from project settings.

To choose which configuration will take action go to "Debug" (Ctrl-Shift-D) and select the appropriate configuration from the drop-down list.

Press F5 again to run debugger.
