convert *.exe files to *.pas files

hello, i have made a program and i converted it to an executable file.  The
problem is that my computer crashed and resulted on me formatting my hard
drive, i hade the copy of the program but i deleted the .pas file.  now i
want to edit my program but i dont know how to convert it back to a working
pascal file.

does any1 have any suggestions on this,

thank you

You're stuck.  There is no good way to automatically reconstruct a PAS
file from the EXE.  Yet another excellent example of the importance of
doing backups (whatever those things might happen to be).

To my knowledge, the only way you can get source code out of an
executable, is to get a disassembler. The problems with disassemblers,
are that they very rarely ever work properly, and they write out
assembler code. It'd be impossible to actually return an executable to
pascal source.

        I'd say your best bet is to go from memory, try
        and code what you already know about your exe.
        If you have norton's utils you could easily re-
        cover your pas file. Other then that you broke it. :}

   This is why the concept called "Backup" is so important - you don't do
backups, you pay the price.  Insofar as creating .PAS for this program,
you'll have to reengineer it from its functionality.  There's no other
choice.

It seems you're searching for a Pascal rev.engineering util..

If the data is not overwritten, you can recover it with a suitable
disk editor.   As for an .EXE -> .PAS converter : there's no such
thing.

You do not need a zip drive to do backups. One can use floppies. Also
Backing up does not necessarily mean that one uses a fancy program and
hundreds of floppies. It can be as simple as after you have ended the
programming for the day insert a floppy in the drive and issue "xcopy
*.pas a: /m" (or /a if you do not want to clear archive attributes on
the files copied). If your code is not worth the floppies and the minute
it takes to copy it then why do you bother to write it in the first
place? If you use pkzip you get also compression and floppy changes when
needed and have several other options like selecting files modified
at the particular date. (Of course just backing up source files does not
help you restoring other important stuff, like autoexec.bat and
config.sys etc. so it is good to have at least one more or less
complete backup)

Btw yo could try using English.

Great. A great way to improve your program. Try to reconstruct your program
and it will be a better version than before.

It is near impossible to decompile and convert back to Pascal source
because program labels, identifier, variables name, types defs... are not
included in the .exe. The best you can do is to disassemble them. I suppose
that won't be useful to you anyway.

No, he could diassemble it and modify it in asm via turbo assembler,
microsoft assembler, or dos debug. Or he could learn macheine code and
just directly modify the machine code. There are other choices.
