There is something that is called a Family Application.  This is a program
that is written in such a way that it will run under DOS and OS/2 without
changes.  The problem is that programs that are coded this way have to be
very generic, and not use OS dependent resources.  Good targets for Family
Applications are things like compilers and line editors and the like.  They
treat the screen the same way (line by line) and use basic file i/o.
I believe that C/2 compiler will have additional info on this.
