rk \*- RK-11/RK03 (or RK05) disk
refers to an entire RK03 disk as a single sequentially-addressed
Its 256-word blocks are numbered 0 to 4871.
Drive numbers (minor devices)
of eight and greater are treated specially.
Drive 8+\fIx\fR is the \fIx\fR+1 way
Thus blocks on rk10 are distributed alternately
Care should be taken in using the interleaved files.
First, the same drive should not be accessed simultaneously
using the ordinary name and as part of an interleaved file,
because the same physical
have in effect two different
names; this fools the system's buffering strategy.
Second, the combined files cannot be used for swapping.
