Almost for 30 years I created most of my programs using (Turbo) Pascal. I have thought about switching to C quite often but now I have a good reason to do so: my two sons have to learn C at school. So daddy cannot stay behind :)
But a lot of my programs have to run under DOS. I mean real DOS, like MS-DOS 6.2 and the real DOS of Windows 98. Thus not a DOS box under, for example, Windows XP. So I am looking for a compiler, preferable an IDE, that can run from an USB stick under Windows 7 64 bit.
Codeblocks can but its EXEs won't run under DOS. Same for Borland's Turbo C for Windows 4.5. (unless I missed a setting)
Borland C++ 3.1 generates the right EXEs but won't run in W7-64.
