******  5/30/82 NOTE - CANNOT BE TRANSLATED AND USED WITH
    CURRENT TRANSLATOR SINCE FORTRAN PRODUCED WILL HAVE
    THE ACODE, SCODE, AND LCODE ARRAYS DIMENSIONED AT 47,
    EVEN THOUGH THE CURRENT TRANSLATOR HAS AN INTERNAL
    CHI OF 156.  THE VERSION THAT SHOULD BE USED IS
    A CORRECTED FORTRAN VERSION THAT SHOULD RESIDE IN 
    THE SAME DIRECTORY AS THIS ALGORITHM.

C   RMARG IS SET TO 80.
C   CHI IS SET TO 156 TO ENABLE USE OF THE EXTENDED CHARACTER SET,
C   CHARACTER CARD ASSOCIATED WITH UNIT 1 BY THE CALL OPENN(1, 0).
C   PRNTR SET TO OUNIT+1 SO THAT (132A1) FORMAT ALWAYS USED FOR 
C     OUTPUT, SINCE UNIX FORTRAN DOESN'T HAVE CARRIAGE CONTROL.
