Michael:

That won't do it, the parameter should be passed as a VARIANT type variable, which I don't know how.

Here is another example, note that the 1st paramenter is diferent in both syntaxis :

Syntax 1
expresión.Save(NoPrompt, OriginalFormat)

Syntax 2
expresión.Save(Comment)

Syntax 1: Requerida. Expresión que devuelve un objeto Documents.
Syntax 2: Requerida. Expresión que devuelve un objeto Versions.

NoPrompt = Type Variant optional.
OriginalFormat = Type Variant optional.
Comment = Type Variant optional.

Here is the VBasic example:

Syntax 1:
Documents.Save NoPrompt:=True, OriginalFormat:=1

Syntax 2:
Documents.Save Comment:="Minor changes to intro"
