	Minor reformatting.
	Add Unreferenced and Warnings (Off) pragmas for cases of
	variables modified calls where they are IN OUT or OUT parameters and
	the resulting values are not subsequently referenced. In a few cases,
	we also remove redundant code found by the new warnings.

	values being ignored.
