Not with the currently released version of strtok, because you have no 
delimiters around the "=" in your example, the complete token being "x=y". 
In next release, i will be supplying an optional form to keep multiple selected 
separators. Even then, there will be multiple passes thru the list of 
separators supplied as the 2nd param of parse(), it will just be hidden from 
you.
