Programming Tips and Gotchas

  • 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.
