Transfers control to a statement label that is represented by a
  variable.  An ASSIGN statement must establish a relationship
  between the variable and the specified statement label.  Statement
  format:

     GO TO v[[,](slist)]

     v      Is an integer variable whose value was set by a
            preceding ASSIGN statement in the same program unit.

     slist  Is a list of one or more labels of executable
            statements separated by commas.

  This feature has been deleted in Fortran 95; it was an obsolescent
  feature in Fortran 90.  VSI Fortran fully supports features
  deleted in Fortran 95.
