 ## Execution control
 
 ```
-hammer-parse-stop-at-input-pos <number>
+hammer-parse-stop-at-pos <number>
 ```
 
 Stops execution once the parsing process reaches past position `<number>` in the input stream. Two caveats: since parsers can consume more than one byte, the argument given is a lower bound of the actual stop position. Additionally, if a parser consumes enough input to reach the requested position, but would later fail, execution is stopped when position `<number>` is reached.
