C
C
C
C THIS PROGRAM WILL PRODUCE FLOW CHARTS OF FORTRAN PROGRAMS
C DIRECTLY FROM THE SOURCE CODE. ALL FORTRAN IV STATEMENTS WILL
C BE PROPERLY HANDLED, AS WILL ALL FORTRAN II STATEMENTS EXCEPT
C IF ACCUMULATOR OVERFLOW, IF QUOTIENT OVERFLOW, AND IF DIVIDE
C CHECK. THE LATTER THREE STATEMENTS WILL BE PRINTED OUT, BUT
C NO FLOW LINES WILL BE DRAWN.
C
C INPUT FROM DEVICE DSK (DEVICE # 1) CONSISTS OF A SEQUENCE OF
C FORTRAN SOURCE IN CARD IMAGE EACH TERMINATED BY AN END CARD.
C
C OUTPUT ON DEVICE DSK1 (DEVICE # 21) CONSISTS OF A LISTING OF
C EACH SOURCE DECK FROM BEGINNING TO END STATEMENT AND EACH
C ASSOCIATED FLOWCHART FOLLOWED BY A LIST OF ALL STATEMENT
C NUMBERS USED BY THE PROGRAM.
C
C OUTPUT ON DEVICE DSK0 (DEVICE # 20) CONSISTS OF A SCRATCH
C FILE FOR EACH SOURCE DECK WHICH IS DELETED AT END OF JOB.
C
