Method definition syntax clarification

[lavsat]

Hello

Code:

object.CheckProperty (PropertyName, PropertyValue, [TimeOut])

CheckProperty ([in] PropertyName, [in] PropertyValue, [in, optional] TimeOut)

From the above examples I know that if a text is within square brackets it is an optional parameter. However, in the object spy i see the example as given in the second statement.

Again, I know that [in] is a required parameter and [in, opitional] is an optional parameter.

My question is, what does that "in" in the brackets really mean.

Thanks,
Satish
