Selecting the Vision Version

You can control what Vision file format is applied to new Vision files through the V_VERSION and filename_VERSION configuration variables. The value of V_VERSION specifies the default format for new Vision files. The filename_VERSION variable allows you to set the file format on a file-by-file basis. Filename is replaced by the base name of the file (the filename minus directory and extension). These variables take an integer value that corresponds to the Vision Version that you want applied (6, 5, 4, 3, 2). For more information about these configuration variables, see Appendix H. Configuration Variables.
