Abstract
A method and system for checking the validity of a sequence of input characters according to the syntactical rules of a selected language is provided. If an input character may not be appended to the previously input sequence according to the rules of the selected language, the newly input character may be prohibited from being appended to the sequence and displayed on the user's computer. Previously input and validated characters automatically may be replaced with a newly input character for formation and display of a valid sequence of characters containing the newly input character. A newly input character may be inserted between two characters of a previously validated sequence of characters. Previously input character sequences may be edited by determining the validity context of previously input sequences of characters.
