\usage{Void set_blocal_var (val, String v)}
\description
  This function sets the value of the buffer local variable with name \var{v}
  to value \var{val}.  The buffer local variable specified by \var{v} must have
  been previously created by the \var{create_blocal_var} function.  \var{val} must
  have the type that was declared when \var{create_blocal_var} was called.
