Can someone please recommend a tool for analyzing, improving, finding "dead code", provide statistics etc. for a source code on COBOL language on VMS/VAX OS and RDB Database?
Thanks.
Some compilers have options for locating dead code, so you may already have the tools you desire. Please keep in mind that there are going to be situations where the code is dead and you cannot tell via static source code analysis.
if a = 1
move 'error' to out-message
end-if
If a can never be 1 then this is dead code. Static source code analysis may not find more complicated instances of this scenario, particularly if the value of a comes from outside the program being analyzed - perhaps a database.
A cursory scan of the static source code analysis tools listed on Wikipedia shows the commercial products are pricy (thousands of euros). The open source tools don't appear to provide much COBOL coverage. You might want to check those out for yourself as I admit I didn't do a thorough evaluation but instead just scanned their documentation.
COBOL is a difficult language to parse.
I have never used it, but the DecSet suite of products includes a product called PCA - Performance and Coverage Analyser. This may be what you are looking for.

I'd like to avoid using eclipse if I can. Tried googling - nothing came up.
The debuggers of most commercial vendors will provide that functionality, for example Kiel MDK-ARM, IAR EWB, Rowley Associates CrossWorks.
Keil and IAR both provide code-size limited evaluation versions that you can use for non-commercial and evaluation purposes (i.e. you can't sell or distribute a product built using it), Rowley have a 30 day evaluation licence (as does IAR in addition to teh code limited version). For a full licence Rowley is by far the least expensive - largely because they use GCC rather than a proprietary compiler, but the debugger is their own and not based on GDB (and all the better for it!).
If you need free tools, CooCox CoIDE appears to do exactly what you want (and probably more). It is Eclipse based, so may not meet your requirements, but all the integration is already done for you, so it is less of a kit-of-parts than assembling Eclipse with CDT and various other plug-ins. In particular the embedded target debugging is integrated, and that is probably the most difficult part to get information on for Eclipse in my experience.

Background
There is a hardware project going on. A hardware accelerator has been being developed by a team of students but there is no general documentation.
There are READMEs here and there, some docxs and in-code (Verilog, C and Lua) comments, but nothing else. The code is written with Vim, versioned with Git and Markdown is our friend, even if we are not on Github (yet).
Since this “thing” is growing, I feel the necessity of writing down something (user manual? developer notes?) but I don't know where to start.
Question
When someone feels the urge of documenting his project, where does it start?
More specifically, what are the generally accepted criteria to do it and what are the best tools?
My hypothetical answer
We quite clearly need both a developer and user manual. One with details of the algorithmic solutions, the other... like for monkeys.
About the tools, I believe that something like a Github Wiki would work fine, but (1) we are not on Github and (2) wouldn't be LaTeX a better way of writing stuff in order to publicise it, eventually. I know we can get our Markdown rendered in a printable way with http://www.cocowrite.com/, but is it the most efficient solution? LaTeX would be a nuisance for collaborative editing and online HTML publishing.
A partial answer can be found here: “What tools are used to write documentation?”.
Second part of the answer can be found here: “What amount of documentation is needed for a non-trivial one-man software project”

I am looking into ways of documenting my code in a JavaDocs kinda way.
Any ideas?
I use UFT 11.52
So far I have seen NaturalDocs + Perl.
Any other ideas?
Thanks in advance.
At least one solution looks
practical,
mature,
is delivered in source code form (consists of one huge (but very professionally written) VBS script that generates the documentation fragments),
and is absolutely free:
VBSdoc, "A VBScript API Documentation Generator"
See http://www.planetcobalt.net/sdb/vbsdoc.shtml.
The author appears to be very competent, given his high SO rep (see https://stackoverflow.com/users/1630171/ansgar-wiechers), and the general quality of his website's content.
Of course, this one is built for standalone VBS scripts, not QTP/UFT scripts. But this should be no obstacle, given the source code is available.
I'd love to hear from you about experiences with this one. Feel free to edit them into this answer, be it accepted or not.
I had success using Natural Docs several years ago. It's one of the few things I blogged about: automated code documentation for QTP
There is a product called Test Design Studio, an IDE alternative for QuickTest and UFT. One of the key features it provides is the ability to generate detailed documentation. It uses XML-style comments to mark up your code, and those comments drive documentation. The same comments also drive detailed IntelliSense for editing your code.
It does exactly what you're talking about.

I want to develop a plagiarism checker for checking several source codes but I couldn't find any proper source code or even a resource to get an idea about it.
I have checked the Boss2 which is useless. they claim that they use Sherlock module for detecting plagiarism but it seems there is no such tools included in boss2.
if any open source detection tool is available for checking source code please let me know.
regards
I'm aware of open-source plagiarism detectors for text (e.g., WCopyFind), but not code.
I couldn't find... even a resource to get an idea about it.
The authors of the excellent closed-source tool MOSS have published a helpful paper about the technology.
I know the question is old, but I did land here from a google.
Sherlock is an open source plagiarism detector. Sherlock's home page is here
I wrote SimiCheck, and you are welcome to use it. If you are interested in an API, I could probably write one very quickly.
I wrote the original algorithm as part of the CrowdGrader peer-grading tool, but then I decided to make the comparison tools available independently.
SimiCheck can handle code, Word (.docx), html, pdf, text, ..., as well as .zip, .tar, .gz, .tgz, and some more formats, and can deal with variable renaming, code moves, code across multiple files, etc.

Are there tools out there which could automatically find copy-and-paste code among a set of files?
I was thinking of writing a script for this, which would just search for equal strings, but such script would find mostly irrelevant equalities. (Such as private final static ...).
Yes, try the Copy Paste Detector.
Our CloneDR is a tool for finding exact and near-miss blocks of code constructed by copy and paste activities.
It can handle systems of millions of lines of code.
It uses precise language grammars to pick out language structures (identifiers, expressions, statements, blocks, functions, classes, packages, ...) that have been copied, and to determine the points of variation across the sets of clones (any of those structures can be parameters!)
CloneDR operates on a wide variety of languages: C, C++, C#, Java, PHP, COBOL, Python, Ada, Fortran, EGL and visual basic (VBScript, VB6, VB.net).
The website has a number of sample clone detection reports from a variety of those languages.
This product is available for evaluation on http://www.semanticdesigns.com. Other open source alternatives are Simian and PMD CPD
