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.
