A 32-bit storage location is available for each memory block allocated; the contents of which are returned by FREEBYTE. This is used to keep track of data when the memory block is used as a stack or a virtual file buffer. The FREEBYTE-counter is initialized to zero when the memory-block is allocated, and update automatically by PUSH POP +STACK -STACK FVREAD and FVWRITE. See section on Memory Management for details.
