Yeah, and eventhough I knew about this problem, it was burried deep in the 
back of my memory.

The manual page has this to say about it:
When picking variable names, make sure you do not choose a name that is 
already taken by an RPN operator. A safe bet it to use lowercase or mixed 
case names for variables since operators will always be in uppercase.

So, using "count" instead of "COUNT" should already be enough.

You're welcome.
