---------------------<sniip>--------------------
he guy who precipitated all this extra discussion was
trying to get the thread oriented to remembering that the key length
must be considered when determining how many blocks will fit on the
track.
That's part of it. There's also code that reads the directory and examines
the key; the buffer length for such code must be 264 rather than 256.
------------------<unsnip>-------------------
BLDL/FIND use a channel programm that still requires a key as well. The
basic search (IIRC) is:
CCW Search-Key-High-Or-Equal
CCW Transfer-in-Channel *-8
CCW Read-Data
Other CCWs in the program are device-dependant, and AFAIK 3390 SLEDs are
still supported.
