Greetings.<br><br>I am just beginning to fiddle around with semantic, for the purpose of writing a language translator.&nbsp; I have not found out how to define multi-character operators, such as ++, += etc.&nbsp; Trying to pick that up from the 
java.bnf file seems to reveal there is no support for multi-character operators on the token level.&nbsp; <br><br>Also the regexp for postfix operators in the bnf definition was given as &quot;[-+][-+]&quot;, which would mean &quot;-+&quot; and &quot;+-&quot; are also accepted as postfix operators (line 628 of 
java.bnf).<br><br>What is the right way to define multi-character operator tokens?<br><br>Thanks,<br>f<br><br>
