A Study of Correlations Between Identified Charged Hadrons
                            in Hadronic Z0 Decays

We present a preliminary study of correlations in rapidity between pairs of
identified charged pions, kaons and protons using the entire SLD data sample of
550,000 hadronic Z0 decays. Short range charge correlations are observed between
all combinations of these hadron species, confirming local conservation of
quantum numbers in the jet fragmentation process, and indicating charge ordering
among these three particle species. The rapidity range of this effect is found
to be independent of particle momentum. A strong long-range correlation is
observed  between high-momentum K^+ and K^-,  and weaker long-range pi^+pi^,
pi^+K^- and p-K^- correlations are observed in light flavor events, providing
new information on leading particle production in u, d and s jets. The
long-range correlations observed in c-cbar and b-bbar events are markedly
different and consistent with expectations based on known decay properties of
the leading heavy hadrons. In addition, the SLC electron beam polarization is
used to tag the quark hemisphere in each event, allowing the first study of
rapidities signed such that positive rapidity is along the quark rather than
antiquark direction. Distributions of signed rapidity, and of the ordered signed
rapidity difference between pairs of particles, provide new insights into
leading particle production and new tests of fragmentation models.
