+BSD AND SYS V SEMANTICS
+
+The user can choose between these two behaviours of the tape driver by
+defining the value of the symbol ST_SYSV. The semantics differ when a
+file being read is closed. The BSD semantics leaves the tape where it
+currently is whereas the SYS V semantics moves the tape past the next
+filemark unless the filemark has just been crossed.

+The default is BSD semantics.
