VBA procedure access level

I would like to make a quick question and very basic on VBA... I found this fine explanation on the web on VBA procedures: Like a variable access, the access to a procedure can be controlled by an access level. A procedure can be made private or public. To specify the access level of a procedure, precede it with the Private or the Public keyword. Next it goes as... The rules that were applied to global variables are the same: Private: If a procedure is made private, it can be called by other procedures of the same module. Procedures of outside modules cannot access such a procedure. Also, when a procedure is private, its name does not appear in the Macros dialog box Public: A procedure created as public can be called by procedures of the same module and by procedures of other modules. Also, if a procedure was created as public, when you access the Macros dialog box, its name appears and you can run it from there And its great, crystal clear! The only thing i wonder is what is the access level of a procedure declared without a Public or Private function? minor question Also if we have a Public keyword can the procedure by called by modules of other workbooks? Thank you for seeing my question
