Two types of messages are given in the Log Window: informational messages and error messages.
The Log Window is divided into two parts: Events and Details.
Here are some of the most common informational messages displayed in the Log Window.

 Message  | 
 Description  | 
| 
 RightMatchSpecial unimplemented  | 
 Indicates _xWILD may have been used at the beginning and/or end of a rule's phrase. This is currently not supported. Try _xANY instead. Or try _xWILD in combination with _xSTART and/or _xEND such that _xWILD does not occur at the beginning or end of the phrase.  | 
| 
 No Rule Reduce: Can’t attach semantic data  | 
 Indicates that an S variable will be discarded, since the rule does not create a suggested node.  | 
| 
 Check: Error in NLP++.  | 
 Indicates a runtime error in a CODE, CHECK, or POST region of a pass file. Possible errors are an NLP++ syntax error or a mismatch between the code and the rules that it applies to. For example, if an optional rule element matched no nodes, but the code attempts to assign a variable to the element's node, this error message will appear.  | 
| 
 Error. Analyzer pass '<NAME>' is uninterned  | 
 Indicates that a pass in the analyzer sequence contains syntax errors and is being skipped over.  | 
| 
 Pat pass given no rules  |
