It’s funny you mention that, as it’s the example I just mentioned to Bob Pierce to demonstrate that there are differences coming from OS-9 to NitrOS-9. It’s also one of the first “gotchas” someone will encounter when trying to learn NitrOS-9 using available OS-9 documentation. tmode syntax is another.

Also some programs have their own built-in help messages. Unfortunately many of these have been turned off in the current NitrOS-9 build. You could edit the source code to turn on the built-in help and recompile the programs.
