How many passes are made through the While loop?

Refer to the following pseudocode, which partially merges the files with internal names FileOne and FileTwo into a third file named Merged. (Each record in FileOne and FileTwo contains a single field of string type.)

Suppose that the contents of FileOne and FileTwo are

FileOne: "Corinne""Marjorie""Shirley""Tamara"

FileTwo: "Arthur""Michael""Sam"

Read FileOne, Namel Read FileTwo, Name2 While (NOT EOF(FileOne)) AND (NOT EOF(FileTwo)) If Namel < Name2 Then Write Merged, Namel Read FileOne, Namel Else Write Merged, Name2 Read FileTwo, Name2 End If End While
