The event-by-event fluctuation of hadronic patterns is investigated by finding a measure of the nonhadronic regions, the voids, for the experimental data of S-32-AgBr interactions at 200 A GeV. Two lowest moments of the event-to-event fluctuation of voids, %26lt; G(q)%26gt; and S-q have been defined by R.C. Hwa and Q.H. Zhang to quantify the dependence of the voids on the bin sizes. Characteristic of the quark-hadron phase transition, if any can be efficiently extracted from the scaling behavior of the voids. The experimental data of Pi(-)-AgBr interactions at 350 GeV/c are also probed with the same tool to have a complete view. The results have been compared with the results of the VENUS generated data for the above interactions.
