That confirms what I thought ... though I think that with the shutter
on P or the lens on A, the exposure compensation knob would adjust
both the ambient exposure and flash output. Isn't that the case on
all Pentax bodies with TTL flash, except for the PZ-1p, where they
finally made flash compensation its own function?

To address a recent thread:
Yes, the exposure compensation knob on a SuperA/Super
Program does, indeed, control the flash output when
the main dial is set to M and aperture is set on the
lens.
Experimental details: Super Program with film speed
set to 200, Sunpak 30DX flash. Metered in a dim room,
flash turned off, manually set 1/4 sec @ f/3.5. With
exposure comp knob at 0, the flash recycled in 2
seconds. With knob at x4 (i.e. 2 stops overexposure)
recycling took 7 seconds. With knob at x1/4 (2 stops
underexposure) recycling was instantaneous. The flash
output visibly varied, too.
Note: if the shutter is on P (program) OR the lens is
on A, the comp knob adjusts the ambient exposure, not
the flash. If the flash is turned on during metering,
things get confusing.
QED.
