Is there a freeware dissassembler with which I can disassemble and old program that I wrote to the source code?

I have looked a bit but haven't found anything that will do it.

Generally, even if you can disassemble, the result will be pretty illegible. Most of the structure of your code is lost when you compile it, so the resulting disassembled code won't have the structure you originally gave it.

Well, I was hoping that I could recover some of the formulas and math without having to do all the research again after 25 years. If that isn't likely to happen then I guess I will just do it the old fashioned way - work for it - again.

Thank you for taking the time to answer,

You'll be able to get the formulas, they'll just be jumbled up. The code will work, it will just be difficult to understand.

 

Is this something like what you want?

You might search for "decompiler" rather than "disassembler."

I downloaded the REC 2.21 and will see how it works.

I also downloaded BOOMERANG from a link on the front page REC site.

Perhaps one of them will work.

Thanks for the help,

you might also want to look into backing up source code i nthe future rather than just the compiled programs. perhaps soemthing like dropbox, i use it to back up a lot of things including source code.

Yes, I have backed up source code from most of my software but I somehow lost the source on two of my favorites. I have always tried to back up everything but over the course of twenty-five years and more than a few computers I have had just two losses. Not a bad record but It seems that I have lost two of my favorites.

It doesn't look like I can use any of the decompilers that have been mentioned so I am going to have to rework the math for my new versions. Such is life.

still, I am grateful for the help I have received here.

thank you all,

Paul

I've done this before to a video game client. The problem is that variables loose their names so you don't know what anything represents and there is no hierarchy of files for organization or anything like that, as Captain said. I don't remember what I used but it was called a decompiler, not a disassembler. Hope you can get your formulas re-worked out without too much trouble.
