My guess would be that the VMS debugger did not know the correct language for your module. Try entering "Set Language C" (or whatever the correct language is) at the debugger prompt. This should allow you to reference lower case and mixed case symbols. I sure with the debugger would change languages automatically based on the module. It's a real pain when your are debugging programs written in more than one language.

Hope this helps!
