We present a search for like-sign dielectron plus multijet events
using 107 pb^-1 of data in ppbar collisions at sqrt s = 1.8 TeV collected in
1992-95 by the CDF experiment.  Finding no events that pass our selection, we
set sigma . Br limits on two SUSY processes that can produce this experimental
signature: gluino-gluino or squark-antisquark production with R-parity
violating deays of the charm squark or lightest neutralino via a non-zero
gamma^'_121 coupling.  We compare our results to NLO calculations for gluino
and squark production cross sections and set lower limits on M(gluino),
M(stop1), and M(squark).
