                  BEGIN marks the start of a  word  sequence  for

                  false.  The words after UNTIL or REPEAT will be
                  executed when either loop is finished.   sys is
                  balanced with its corresponding  AGAIN    UNTIL

SHORT DEFINITION: Leaves the address of the block buffer contain-
                  ing block u.
LONG DEFINITION : addr is the address of the assigned  buffer  of
                  the first byte of block u.  If the block occupy-
                  ing that buffer is block u and has been UPDATEd
                  it is transfered to mass storage before assign-
                  ing  the buffer.   If block u is not already in
                  memory,  it is transferred  from  mass  storage
                  into an assigned block buffer.  A block may not
                  be  assigned to more than one buffer.   If u is
                  not an   available block,  an  error  condition
                  exists.    Only  data  within  the  last buffer
                  referenced by BLOCK or BUFFER is  valid.    The
                  contents  of a block buffer must not be changed
                  unless the change may  be  transfered  to  mass
                  storage.

LONG DEFINITION : When used in the form:  COMPILE BRANCH
                  an  unconditional branch operation is compiled.
                  A branch address must be  compiled  immediately
                  following this compilation address.  The branch
                  address  is  typically  generated  by following
                  BRANCH with <RESOLVE or >MARK .

                  buffer on the stack.
LONG DEFINITION : Assigns a block buffer to block u.  addr is the
                  address  of  the first byte of the block within
                  its buffer.   This function is fully  specified
                  by  the definition for BLOCK except that if the
                  block is not already in memory it might not  be
                  transfered from mass storage.   The contents of
                  the block buffer     assigned  to  block  u  by
                  BUFFER are unspecified.
