This is completely wrong...where did you get your information?
The only non-graphical version of OS/2 was version 1.0. Version 1.1, released
in 1988, was the version that introduced the Presentation Manager. What OS/2
2.0 introduced was the Workplace Shell, the object-oriented shell sitting on
TOP of the Presentation Manager.
As for OS/2 text mode programs, these are nothing like DOS programs (And never
were). OS/2 is (and always was) a proper operating system in that it provides
APIs for program control, File/Disk operations, screen/video, Mouse
operations, etc.
Because of lack of information or some other reason, you don't know that there
are serious differences between OS/2 text-mode programs and DOS programs.
Further, you don't seem to know that OS/2 provides two _separate_ command-line
interfaces; DOS and OS/2.
OS/2 was never just a protected-mode DOS...it's always been quite a different
beast. :)
