Although this can mean various things, I usually see when trying to BLOAD a
file into an area of memory that ProDOS knows is in use.  ProDOS keeps a 
bitmap of memory (kind of like the one on a disk) and will complain if you try 
to overwrite used memory.  (example: bload'ing a file which would overwrite 
BASIC.SYSTEM or the ProDOS kernel is not allowed..)  Sometimes older programs 
would BLoad in over the text page to effectively print a message while the 
file loaded. Prodos won't allow it, because it knows the text page is reserved.
