1. A text recognizer comprising a non-cumulative character recognition module for providing an indication of the likelihood that a given character is present in a handwritten input at a position starting at a start vector and ending at an end vector, the recognition module coupled to a forward search module to enable multiple parallel non-cumulative scores to be delivered from the character recognition module to the search module, wherein the character recognition module has means for delivering a first out-of-range message to the forward search module indicative of an inability to score a handwriting recognition theory in response to a request from the forward search module defining a selected character theory which encompasses insufficient number of stroke vectors for a character recognition operation to be completed.
