I have an old dos.exe program (400mb in size) that runs on windows 95 I think, however this program mainly operates in dos mode. It works on old packaging machinery at work. It's function is to monitor switches, sensors, some hall effects and stop, start of the equipment. My question here is I tried copying the program to my PC as a backup and I tried to view this on my PC,so that I could view what was inside this program. Just curious. All I've seen is jumbled letters and codes, more likely as an encryption. Is there any way to unscramble this code and view it a an ordinary file or have they done this for copy write purposes.

That's exactly what I would expect to see in an EXE. BTW, if 400mb means 400MB, it seems like a stretch. Dunno how DOS can load 400MB into memory. ===================================== If at first you don't succeed, you're about average. M2

I think I better change that value to 416Kb (420,000 bytes)instead of 400mb. Sorry that was a little bit to high.

Unless the code is scrambled these might help http://www.thefreecountry.com/progr... http://www.debugmode.com/dcompile/d...
