C     RENBR(REBIG/CHANGE SIZES OF ARRAYS IN RENBR)
C
C     DONALD BARTH, HARVARD BUSINESS SCHOOL
C
C     THIS PROGRAM CAN BE USED TO CHANGE THE MAXIMUM SIZE  OF  AN
C     INDIVIDUAL  MAIN  PROGRAM OR ROUTINE WHICH CAN BE LISTED BY
C     RENBR.  FOR LARGE PROGRAMS, IF THIS IS OOT DOOE,  THEO  THE
C     LISTINGS  WILL  BE  INTERRUPTED BY PARTIAL STATEMENT NUMBER
C     TABLES OR CROSS REFERENCE TABLES WHENEVER THE  ARRAYS  USED
C     TO  STORE  THESE  FILL.   THIS PROGRAM ASKS FOR THE VARIOUS
C     MAXIMUM NUMBERS OF ITEMS  WHICH  MUST  BE  ALLOWED  FOR  IN
C     LISTING A PROGRAM, AND CALCULATES THE DIMENSIONS FROM THESE
C     ANSWERS.  BOTH THE RENBR MAIN PROGRAM, ALL OF ITS ROUTINES,
C     AND  THE  VERSION OF THE REUSER ROUTINE BEING USED, MUST BE
C     PROCESSED USING THE SAME ANSWERS TO THE QUESTIONS.  TO SAVE
C     EFFORT, THE RENBR MAIN PROGRAM, ITS ROUTINES AND THE REUSER
C     ROUTINE CAN ALL BE APPENDED INTO A SINGLE FILE BEFORE BEING
C     PROCESSED.    THE  RESULTING  VERSION  OF  THE  RENBR  MAIN
C     PROGRAM, ITS ROUTINES AND THE  REUSER  ROUTINE  SHOULD  NOT
C     SUBSEQUENTLY  BE  PROCESSED  AGAIN, SINCE THE STRINGS BEING
C     SEARCHED FOR INCLUDE THE  ORIGINAL  ARRAY  SIZES.   IF  THE
C     ARRAY  SIZES  SUBSEQUENTLY  MUST  BE  INCREASED,  THEN  THE
C     ORIGINAL VERSION OF THE RENBR MAIN PROGRAM,  ITS  ROUTINES,
C     AND   REUSER  SHOULD  BE  PROCESSED  AGAIN.   EVEN  WITHOUT
C     CHANGING THE SIZES OF THE ARRAYS, RENBR  CAN  RENUMBER  ANY
C     INDIVIDUAL  MAIN  PROGRAM  OR ROUTINE CONTAINING UP TO 1000
C     NUMBERED STATEMENTS.
