in the POM.pdf on chapter "Model Writing" Model Writing Notes part, it shows the following codes fragment:

200 IF (CON(J).GT.2.*DELT) GO TO 210
    STATE(K)=ECOMP(I)
    STORE(K)=ECOMP(I)
    GO TO 220
210 DSTATE(K)=(ECOMP(I)-STATE(K))/CON(J)
220 VERROR=VREF(I)+VOTHSG(I)-STATE(K)

what is STORE , the manual only says it is a integrator memory, but does give an example. so here why use store can solve small time constant problem? what is the theory and formulas behind STORE variable?

With those lines the time constant block is ignored when the time constant is less or equal to 2 time steps. If so, out signal is same as input signal, i.e. no time constant.
