We consider the (1+1)-dimensional ${\cal N}=(2,2)$ super Yang--Mills theorywhich is obtained by dimensionally reducing ${\cal N}=1$ super Yang--Millstheory in four dimension to two dimensions. We do our calculations in thelarge-$N_c$ approximation using Supersymmetric Discrete Light ConeQuantization. The objective is to calculate quantities that might beinvestigated by researchers using other numerical methods. We present aprecision study of the low-mass spectrum and the stress-energy correlator$<T^{++}(r) T^{++}(0)>$. We find that the mass gap of this theory closes as thenumerical resolution goes to infinity and that the correlator in theintermediate $r$ region behaves like $r^{-4.75}$.Comment: 18 pages, 8 figure
