VMS IDE is an integrated development environment that enables you to quickly and easily develop comprehensive applications for OpenVMS system. It provides a set of tools for developing, building, and debugging OpenVMS projects.


  • Source code synchronization between the local machine and OpenVMS system.
  • SSH connection setup to the remote OpenVMS system.
  • Projects Explorer as a simple and convenient way to manage OpenVMS projects.
  • Debugger for OpenVMS and JVM projects.
  • Highlighting for MMS, CLD, MSG, Pascal, Fortran and Cobol source files.
  • Light-weight IntelliSense for CLD, MSG, Pascal, Fortran and Cobol.
  • Supported languages: C, C++, Fortran, Cobol, Pascal, Basic, Bliss, Java, Kotlin, Scala.


  • The VMS IDE extension can only be used in conjunction with ODS-5 OpenVMS file systems; it cannot be used with ODS-2 file systems.
  • Do not use the minus sign ("-") in file names. This may prevent the debugger from finding the source file.
