Let's see: V3.3, IOP about ...

• f'(x): On return, Y, Z, and T will be cleared and the position x will be in L.
• SLV: It returns xroot in X, the second last x-value tested in Y, f(xroot) in Z, and 0 in T. Additionally, SLV acts as a test, so the next program step will be skipped if SLV fails to find a root. Then it points to a footnote stating: Please refer to the HP-34C Owner’s Handbook and Programming Guide (Section 8 and App. A) or the HP-15C Owner’s Handbook (Section 13 and App. D) for more information about automatic root finding and some caveats.
• Integrate: ∫ returns the (approximated) integral in X and an upper limit of its uncertainty in Y. Additionally, it points to a footnote stating: Please refer to the HP-34C Owner’s Handbook and Programming Guide (Section 9 and App. B) or the HP-15C Owner’s Handbook (Section 14 and App. E) for more information about automatic integration and some caveats.
• Π and Σ doesn't contain any remarks alike. I'll check what happens there. Thanks for reporting.
  Addendum: Hmmmh, Π and Σ clear all stack levels except X. Though I've no idea why. Pauli?
