explanation of format.

20 14 Character 8 SYTSYG_XCTMSACT Accumulated elapsed time in
microseconds that routines that
comprise user exits were active
28 1C Unsigned 4 SYTSYG_FTRDONE Number of times fast CCW
translation processing completed
successfully for a DASD device.
32 20 Unsigned 4 SYTSYG_FTRABORT Number of times fast CCW
translation processing was aborted
for a DASD device.
36 24 Unsigned 4 SYTSYG_FTRNOTEL Number of times a presented CCW
for a DASD device was not eligible
for fast CCW translation. There
are cases where ineligibility may
have been determined before the
CCW is presented to the fast path
simulator. Those cases are not
counted here.
40 28 Unsigned 4 SYTSYG_FTRWRITE Number of times a write channel
program for a DASD device was
presented for fast CCW
translation.
44 2C Unsigned 4 SYTSYG_CTNDONE Number of times fast CCW
translation processing completed
successfully for a network device.
48 30 Unsigned 4 SYTSYG_CTNABORT Number of times fast CCW
translation processing was aborted
for a network device.
52 34 Unsigned 4 SYTSYG_CTNNOTEL Number of times a presented CCW
for a network device was not
eligible for fast CCW translation.
There are cases where
ineligibility may have been
determined before the CCW is
presented to the fast path
simulator. Those cases are not
counted here.
