I'm looking for software that will "analyze" my Pascal files and give me information like this:

        1.      Which variables are not being used
        2.      A list of procedures/functions and their callers
        3.      Procs/funcs that are not used
        4.      General overview of program flow (what calls what, given primary file starting point).

We have a directory (BP7) that contains more than 150 source files that are all part of a single application.  Obviously, it'd be great to have something that would tell us these things and help to maintain it.

Anyone seen anything like this?  I wish we could run the old FoxDoc program (came with FoxPro) on it -- FoxDoc produced very informative reports.

Since Michael Hermann asked, here's what I'd envision as the input and output for such a program:

Input (on command line):

        > panalyze *.pas /out=outfile.lis

Output (into file outfile.lis):

Function/Procedure
    Program         Referenced
------------------------------------------------------------------
Get_Data
    *Program1.pas   <defined>
    Program2.pas    Read_User_File
                    Process_New_User_File
    Program3.pas    Read_Operator_Files

Display_Sensor_Info
    Program2.pas    Operator_Processing
    Program5.pas    Join_User_Data
   *Program8.pas    <defined>

Shutdown_Probe1
   *Program2.pas    <defined>
------------------------------------------------------------------

This output tells me that the Function or Procedure "Get_Data" is defined in Program1.pas and is called (referenced) in two procedures (named Read_User_File and Process_New_User_File) in Program2.pas and one procedure in Program3.pas.

It also tells me that "Shutdown_Probe1" isn't used at all -- it's only defined.

Of course, it would help if the listing was alphabetized by Function/Proc name. That is, in this list "Get_Data" and "Display_Sensor_Info" would swap places.

I'll leave a note for Borland asking them if they have anything similar.  The Turbo Profiler doesn't do this -- it provides an analysis of a running program and includes mostly timing information.

How about a tree starting from left going to the right.
Or a structure diagram facing the usual way (down).

I think I could use that, remember to include support for units which are
called and which have proc's & func's not used by client code. This would be
ideal way to see if theere is too much old or unused code in a library.
