Modifications to existing C Code

Project relates to a series of medical instruments. The code and design go back 30 years. The original devices boot DOS and run their C code program all on a floppy disk. In 2011 DOS and the program were modified and moved to run on a 'C' hard drive basis however an 'A' floppy disk was still used for saving of backup/recovery data. We now need this to be changed within the code to save this backup/recovery data to a USB drive instead of the 'A' floppy. We intend to update the whole device next year and will be looking to rewrite the program into a windows application format. If you feel you are suitably skilled it would be good to discuss this as well. Many thanks, David

I am very proficient in c and c++. I have 16 years c++ developing experience now, and have worked for more than 7 years. My work is online game developing, and mainly focus on client side, using c++ under Windows environment. I made many great projects using c++, for example, I made the tools which could convert java codes into c++ scripts, of course garbage collection included, this was very similar to a compiler, and was very complex. I also made our own mobile game using c++, I can show you the demo of client, if you like. I am very proficient in java also. I have a very good review on Freelancer.com, I never miss a project once I accept the job, you can check my review. Trust me, please let expert help you.

Hi! I'm experienced (20+ yrs) developer with excellent knowledge of C language, familiar with all ancient coding practices ;-), I still remember MSDOS os. I also have commerical experience in porting old applications to modern platforms so i think it makes me the best candidate for this project. Does your device still run MSDOS ? or it uses windows but your application is started in dos compatibility mode?

Wow! Your project is pretty interesting to me, because it's so unusual! I mean to find a DOS app project in 2017 it's something that you don't usually expect :) Anyway, I'd like to know more details about the project. As far as I understood your issue is an inability to work with drive letters except 'A'. I haven't seen the source code yet, but it could be pretty straightforward to change 'A'-letter drive to something else ( as the first attempt it could be hardcoded letter, or more flexible - config file, or interactive menu, or app's command line argument). Anyway, could you provide the source code? At least partially ( if you can provide the specific part which is responsible to save to the 'C'-drive now it would be perfect ). I haven't been programming for DOS may be for 20 years already, but I would really like to have! (Watcom C compiler, Turbo Assembler, int21h, oh.. sweet memories :)) P.S.: I forgot to ask. Currently the program is running under vanilla DOS? Or under an emulator like DOSBox ?

I had been writing c (and c++) code since1995. My role as a s/w engineer in a large multinational corp instilled a rigor of writing code that was clear, well documented and could be understood and supported by other engineers later on. This rigor continues to this day and I am very confident that i will be able to meet the requirements for the project. As far as my 4 moths of freelance career is concerned, I have been able to net 3 assignments so far. Of these three assignments, 2 are from the same employer/person. The reviews demonstrate that i have the capability and willingness to deliver the goods. I have good communication skills and am able to understand the requirements quickly. My coding skills are also very good. As I understand it, the initial project would be to change the target for the backup/recovery data from a floppy drive to a USB drive. is there any reason why the modification in 2011 did not include changing the backup methodology ?
