The following changes are necessary in /text/sbasic/shared/03060200.xhp:

Re:
Sub ExampleEqv
Dim vA as Variant, vB as Variant, vC as Variant, vD as Variant
Dim vOut as Variant
vA = 10: vB = 8: vC = 6: vD = Null
vOut = A > B Eqv B > C REM returns -1
vOut = B > A Eqv B > C REM returns -1
vOut = A > B Eqv B > D REM returns -1
vOut = (B > D Eqv B > A) REM returns 0
vOut = B Eqv A REM returns -1
End Sub

1. "A", "B", "C", and "D" are used without initialization, and vA, vB, vC, and
vD are initialized but unused yet. 
"vA" -> "A", "vB" -> "B", "vC" -> "C", "vD" -> "D"
2. "B > A Eqv B > C REM returns -1" -> "B > A Eqv B > C REM returns 0"
3. "A > B Eqv B > D REM returns -1" -> "A > B Eqv B > D REM returns 0"
4. "(B > D Eqv B > A) REM returns 0" -> "(B > D Eqv B > A) REM returns -1"
5. "B Eqv A REM returns -1" -> "B Eqv A REM returns -3"
