RC_HAND ($08), IX is not a valid memory handle

RC_ERR ($0F), if BC > 256 bytes, fatal error

Notes
Block allocation (more than one or 256 bytes) is implemented since OZ 4.7. Up to one bank can be requested (16384 bytes).
If such a large block is requested (more than 256 bytes), MM MM_MUL has to be specified in OS_Mop.
