The following FORTRAN routine assigns text value to CHAR80 
string variable. N8 is the number of register (or array) to 
assign to CHAR80. 

The blkcom.ins pass auxiliary variables, as MONCAS, etc,. 

The routine reads a direct access file if LUNTEX > 0, ans 
assign the string variable if LUNTEX < 0

Other tests are done if other conditions are satisfied, but 
this are not of importance for the problem in hands.

      SUBROUTINE READ11 ( N8, CHAR80 )
      IMPLICIT REAL*8 (A-H, O-Z),  INTEGER*4 (I-N)
      INCLUDE  'blkcom.ins'
      EQUIVALENCE   ( MONCAS(138),  LUNTEX )
      EQUIVALENCE   ( MONCAS(145),  KOMPAR )
      CHARACTER*80  CHAR80, dmup
      common /killcode_mup/ dmup(7653)
      DATA  KDATE  /  -7722  /
      IF ( LUNTEX .LE. 0 )  THEN
      IF ( KDATE  .NE. -7722 ) GO TO 2864
      IF ( KOMPAR .LT. 4     ) GO TO 2864
      KDATE = 0
      DO 5942  J=1, 9999
      K = INDEX ( DMUP(J),
     1 'Consult the 860-page ATP Rule Book' )
      IF ( K .EQ. 0 )  GO TO 5942
      DMUP(J+1)(11:31) = 'A.   Program is no ol'
      DMUP(J+1)(32:80) = 'der than March, 1996.'
      GO TO 2864
 5942 CONTINUE
      STOP 'Halt in READ11.  No March, 1996.'
 2864 CHAR80 = DMUP(N8)
      ELSE
      READ (UNIT=LUNTEX, REC=N8)  CHAR80
      CHAR80=DMUP(N8)
      ENDIF
      RETURN
      END

I don't know if the extra '_' as added by f2c are or not 
cause of some trouble.
