I need to parse an input set of characters with the following results :
If char = 'a' goto next state else call error 
This logic would be used for every character in the string. The intent is to 
show exactly where the failure has occurred on the input string versus the 
expected string. 
Ideally the error call could have a parameter such as an offset to indicate 
where within the string the match failed. 
Any ideas would be greatly appreciated.
