I am a beginner at creating XCMDs in LSC 3.0. I am implementing a few
of my choice Home stack interpreted functions. I am still learning simple
string manipulation; how to allocate enough space for the return string, etc.
Each time my XFCN is called, I allocate a new Handle for a return value, 
which I then fill up with a zero-terminated string. My question is: how does
that handle ever get disposed of? If I dispose of it before exiting the
XFCN, that just throws away my return value. Is there a way to mark the
handle for later purging?
