We discuss a heterotic-string solution in which the observable sector
effective field theory just below the string scale reduces to that of the MSSM,
with the standard observable gauge group being just SU(3)_C x SU(2)_L x U(1)_Y
and the SU(3)_C x SU(2)_L x U(1)_Y-charged spectrum of the observable sector
consisting solely of the MSSM spectrum. Associated with this model is a set of
distinct flat directions of vacuum expectation values (VEVs) of fields that all
produce solely the MSSM spectrum. Some of these directions only involve VEVs of
non-Abelian singlet fields while others also contain VEVs of non-Abelian
charged fields.Comment: 5 pages. Latex w/ sprocl.sty. Talk presented at PASCOS 9
