      SUBROUTINE WRITE(X,N,NNLINE,IWIDTH,IDEC)
C
C     PURPOSE--THIS SUBROUTINE WRITES OUT THE CONTENTS
C              OF THE SINGLE PRECISION VECTOR X IN AN ORDERLY
C              AND NEAT FASHION.
C              THIS SUBROUTINE GIVES THE DATA ANALYST THE ABILITY
C              TO GET DATA OUT OF THE MACHINE WITHOUT HAVING
C              TO WORRY ABOUT AND SPECIFY FORMATS.
C     INPUT ARGUMENTS--X      = THE SINGLE PRECISION VECTOR OF
C                               OBSERVATIONS TO BE PRINTED OUT.
C                    --N      = THE INTEGER NUMBER OF OBSERVATIONS
C                               IN THE VECTOR X.
C                    --NNLINE = THE INTEGER VALUE 
C                               OF THE DESIRED NUMBER OF
C                               OBSERVATIONS IN X TO APPEAR PER LINE. 
C                    --IWIDTH = THE INTEGER VALUE 
C                               OF THE LARGEST NUMBER OF
C                               CHARACTERS THAT A VALUE IN X MAY TAKE UP
C                               = THE DESIRED NUMBER OF INTEGER DIGITS
C                               + THE DESIRED NUMBER OF DECIMAL DIGITS
C                               + 1 DIGIT FOR THE SIGN
C                               + 1 DIGIT FOR THE DECIMAL POINT.
C                               (NO PROVISION NEED BE MADE FOR LEADING
C                               OR TRAILING SEPARATION BLANKS--THIS IS
C                               DONE AUTOMATICALLY BY THE SUBROUTINE.)
C                    --IDEC   = THE INTEGER VALUE 
C                               OF THE DESIRED NUMBER OF
C                               DECIMAL DIGITS TO BE PRINTED OUT.
C     OUTPUT--A LISTING OF THE N VALUES OF THE DATA VECTOR X
C             WITH NNLINE VALUES PRINTED PER LINE, AND WITH 
C             BLANKS AUTOMATICALLY INSERTED BETWEEN ADJACENT VALUES.
C             A BLANK LINE WILL APPEAR AFTER EVERY TENTH LINE.
C             50 LINES OF DATA WILL APPEAR PER PRINTER PAGE.
C     PRINTING--YES.
C     RESTRICTIONS--NNLINE MUST BE 1 OR LARGER;
C                 --IWIDTH MUST BE 2 OR LARGER;
C                 --IWIDTH MUST BE 12 OR SMALLER; 
C                 --IDEC MUST BE 0 OR LARGER;
C                 --IDEC MUST BE (IWIDTH-2) OR SMALLER;
C                 --THE PRODUCT OF NNLINE AND (IWIDTH+1) MUST
C                   BE 131 OR SMALLER.
C     OTHER DATAPAC   SUBROUTINES NEEDED--NONE.
C     FORTRAN LIBRARY SUBROUTINES NEEDED--NONE.
C     MODE OF INTERNAL OPERATIONS--SINGLE PRECISION.
C     LANGUAGE--ANSI FORTRAN. 
C     COMMENT--THE LISTED VALUES ARE TO BE READ ROW BY ROW--
C              THAT IS, THE FIRST VALUE IN X APPEARS
C              ON ROW 1, COLUMN 1 OF THE OUTPUT,
C              THE SECOND VALUE IN X APPEARS ON ROW 1, COLUMN 2,
C              ETC. 
C     REFERENCES--NONE.
