We . look at two of the tasks involved in the compilation process. break the source code into lexemes units .

Trier in the . 1930. s, whose version is seen as a new phase in the history of semantics. What has now come to be known as the theory of semantic fields (or field-theory) was first put forward as such by a member of German and Swiss scholars in the 1920s and 1930s. . Languages.
