[求助]按條件進行統(tǒng)計的程序編寫

以AB AE為例編寫如下

N:=BARSLAST(DATE<>REF(DATE,1))+1;

NN:=BARSLAST(A)+1;

N1:COUNT(B&&EXIST(E,NN)=0&&NN<=N,N);

N2:COUNT(E&&EXIST(B,NN)=0&&NNN<=N,N);

模型僅供參考

N:=BARSLAST(DATE<>REF(DATE,1))+1;

NN:=BARSLAST(A)+1;

NNN:=BARSLAST(C)+1;

N1:COUNT(B&&EXIST(E,NN)=0&&NN<=N,N);

N2:COUNT(E&&EXIST(B,NN)=0&&NNN<=N,N);

N3:COUNT(D&&EXIST(F,NNN)=0&&NNN<=N,N);

N4:COUNT(F&&EXIST(D,NNN)=0&&NNN<=N,N);
