[antlr-interest] how to best break apart multiple assignments

[Bruce Bauman]

In the sometimes bizarre dialect of Pascal I am using (MetaWare), the following is allowed:
 
Odd := Even := 0;
 
I need to split this into:
 
Odd := 0;
Even := 0;
 
Can somebody point me in the right direction?
 
Thanks.
