Indicates the major version (1, 2, etc.) of the scripting language currently in use.
The following table lists the versions of VBScript through 5.0, as well as the year in which they were released and the products with which they were initially released:
Internet Explorer 3.0
Internet Explorer 4.0, IIS 4.0, WSH 1.0, Outlook 98
Visual Studio 6.0
Internet Explorer 5.0
Internet Explorer 5.5
Microsoft Visual Studio .NET
The function is also implemented in the JScript script engine.
If your script requires some functionality available in a baseline version, ordinarily you want to make sure that the script is running on that version or a later version. For instance, if your script requires regular expression support, which became available only in VBScript Version 5, you would test for the version with a code fragment like:
If ScriptingEngineMajorVersion >= 5 Then
You do not want to test for equality, as in:
If ScriptingEngineMajorVersion = 5 Then
since that may leave your script unable to run on versions of VBScript later than Version 5.
This function is not supported in VBA.
