i have this:

    Dim split As String() = temp_string.Split(",")

    ''#feed all info into global variables
    patient_id = split(0)
    doc_name = split(1)
    lot__no = split(2)
    patient_name = split(3)

No need to do anything. The garbage collector will do its jobs clearing the variable. Explicitly set every variable to nothing will slow down your application.

You can always set it to Nothing which will clear the reference. Then the garbage collector will take care of the rest when it finds that to be a good idea.

split = Nothing

However, if this is a local variable of a method you would typically not need to worry about this, the array will be available for garbage collection as soon as it goes out of scope.
