I have inherited a large amount to F77 code which does not use IMPLICIT NONE. Is there a tool to automatically add IMPLICIT NONE and the relevant variable definitions to all the source?

Polyhedron's SPAG can do this and more.
However, just adding declarations using a tool will not do away with the need for manual intervention to detect and remove unused variables, incorrect declarations or slightly misspelled variable names.

Hi
This is probably not "diplomatically correct" -- but check-out refactoring tools provided by Photran 6.0. You can do quite a few things including adding implicit none and removal of unused variables. Of course, no-one (including SPAG other such tools) gives 100% guarantee.

Using Visual Studio's Find in Files for entire solution for "subroutine"
Insert IMPLICIT NONE in the first appropriate file
Copy to Paste buffer
Then click on next file, look and conditionally paste.
The do the same thing for "function".
You should be able to do this in under 5 seconds per occurance.
720 subroutines/functions per hour.
Also, the walk-though may be beneficial for noticing additional conversion/maintenance issues.
I'd suggest putting comment markers in a side file (issues file)as you detect issues. Use a unique comment indicator, perhaps your nameinitials plus sequence number. Paste a copy of the new comment into the source file for use later.
The when prior issue detected simply copy and paste the comment into the file as you perform the insertion of IMPLICIT NONE.
When you have the IMPLICIT NONE pass complete, save your comments file.
I would suggest attempting a Build before addressing the additional issues in the issues file.
Note, your first issue might read"
! Ferrad 001 - Insert IMPLICIT NONE in subroutines and functions (copy and paste from following line)
IMPLICIT NONE
! Ferrad 002 - Move COMMON to Module
! Ferrad 002 - ...
and so on.

You could also look at the fntcheck tool for Fortran 77, or the various f77 to f90 free tools.
Or write a small utility in (say) Basic to open all your .f?? files and write IMPLICIT NONE after the first PROGRAM, SUBROUTINE or FUNCTION statements - you may want to check for multi-line statements ...

I tried SPAG but unfortunately it does not look (consistently) inside USE'd modules for variables and inserts declarations in the SUBROUTINE as well, so I end up with vast amounts of duplicate variables.

Thanks Jim, but I actually want the declarations too. I looked at SPAG but it has problems with modules, so I'll take a look at Photran.

I am not sure what you tried; perhaps you can show a small example for which your SPAG run produced duplicate variables. Secondly, modules are an extension to Fortran 77, so there is a question as to which extension of Fortran-77 you use.
Nevertheless, given the input

The problem appears to be caused by modules which USE other modules. Example below:
ALLMODU.FOR:
module MaxMaterialCodes
INTEGER, PARAMETER :: NNMATC = 10
end module MaxMaterialCodes
MODULE PROBOL
USE MaxMaterialCodes
INTEGER NNIN
END MODULE PROBOL
REDMATC.FOR:
SUBROUTINE REDMATC
USE PROBOL
IMPLICIT REAL(8) (A-H,O-Z)
DO 100 j = 1 , NU
DO 50 i = 1 , nnmatc
NCUmp = NCOmp+1
50 CONTINUE
100 CONTINUE
RETURN
END

To rewind back to your original question ... you can try using the command line option
/warn:declarations
That essentially does an "implicit none" for each program unit.

Yes, good idea. However it means I'll have to write a parser to convert the compiler output into the relevant declarations and put them into the code.

Hi ferrad01
Did you try Photran? Below are two sample results.

Case 1:
Subroutine Test
do i=1,N
NC = NC + 1
end do
End Subroutine Test
Refactoring (Introduce Implicit None) gives
Subroutine Test

Case 2:

Before I jump through the hoops required to install this, can it do nested modules as in my simple example I posted above which fails in SPAG?

So it looks like it deals with nested USE's, so I'll look into using it now.

I apologize that I am perhaps taking too much liberty to discuss the issues not exactly related to IVF --
Ferrad01, what does it complain about? Java parsing error or something else? Do you get something like unexpected character in column 1 line 3? Is it possible to give some more details of the error log?

Can you post the error log?
Some tips, related to eclipse/photran, that might help:
- The latest version of eclipse tends to misbehave when installed to a read-only location ---Not sure if that might be your problem, though.
- Try increasing the maximum amount of memory java can use ---in the past, the "implicit none" feature required about 3 GB per every 5000 lines of code (not sure if that has improved).
- photran uses its own dialect of fpp (i.e., it gives errors for things Intel's fpp and GNU's cpp accept without problem), so that might complicate things.
