INDEX IS A FORTRAN CROSS REFERENCING PROGRAM. A FORTRAN SOURCE
FILE PROCESSED BY INDEX WILL BE CHECKED FOR ALL OF ITS VARIABLE NAME
AND LABEL USEAGE. THE RESULTS WILL THEN BE LISTED IN ALPHABETICAL
ORDER, LISTING ALL THE VARIABLE NAMES AND LABELS USED IN THE PROGRAM,
THE LINES ON WHICH THEY WERE USED, AND HOW THEY WERE USED. IF NEEDED,
THE VARIABLES FROM SPECIFED FORTRAN SOURCE FILES CAN BE SAVED
ALONG WITH THOSE OF OTHER FORTRAN SOURCE FILES AND LATER PRINTED OUT
AS A SUPER INDEX GIVEING VARIABLE NAME AND THE NAMES OF ALL THE
FORTRAN SOURCE MODULES IT WAS USED IN. ALSO INCLUDED IS THE CAPABILITY
TO EXCLUDE FROM THE INDEX LISTING ALL VARIABLES THAT ONLY APPEAR IN A
FORTRAN SOURCE MODULE IN A COMMON BLOCK ,TYPE OR EQUIVALENCE
DECLARATION BUT ARE NOT USED ELSEWARE(OR LIST ONLY THOSE IF WANTED).
THE USER CAN ALSO LIST ONLY THOSE VARIABLES THAT ARE GLOBAL (DEFINED
IN A COMMON BLOCK) OR THOSE THAT ARE LOCAL. A VARIATION OF THE
SUPER INDEX IS AVAILABLE TO LIST (ALMOST)ALL ENTRY POINTS, THE MODULES
THAT THEY ARE DEFINED IN, AND ALL THE ENTRY POINTS THAT CALL THEM AND
THAT THEY CALL.
INDEX WILL HANDLE ALL SOURCE FILES WRITTEN IN FORTRAN FOUR AND
FORTRAN FOUR PLUS IN ACORDANCE WITH 'PDP11 FORTRAN LANGUAGE REFERENCE
MANUAL' (DEC-11-LFLRA-C-D) AND THE FORTRAN 1977 STANDARD.
INDEX CAN BE GENERATED TO RUN UNDER THE RT-11 OR RSX-11M
OPERATEING SYSTEMS.
