The Debugger cannot reference a variable unless it is defined in a 4GL module. For 4GL variables, check that you entered the variable name correctly. If the variable is not in the current function or module, you must qualify its name. See the section on "Scope of Reference" in the Debugger manual. (This message can appear if you enter what you intend to be a module name in a BREAK or TRACE command, but you omit the dot at the end of the name.)
