Mark -

It's true there is no simple way to do this.  Just to get you going though, here are two possibilities off the top of my head:

1.  Arrange to pass IN a LargeNegativeInteger to be cloned, or class LNI to be instantiated, and use that.

2.  Pass your 32-bit value back as a LargePositiveInteger, and then use logic like...

	valueAsLPI := self primitiveZort.
	signedValue := (valueAsLPI bitAnd: 16r80000000) = 0
		ifTrue: [valueAsLPI]
		ifFalse: [(valueAsLPI bitInvert32 + 1) negated]

Hope this helps.
