[菊花烧饼]

if (ibsta & 0x8000)
              {
    testData->replaceStringFuncPtr(&testError->errorMessage, errorMessage33120A);
          testError->errorFlag = TRUE;
          testError->errorCode = ibsta;
    return;
              }
        else
              { 
              }

how can use case structure like if else  when fail case i need do nothing.

    in my attached

    i want to find the elemet of array include"input",but  output include blank array,because the false can not be empty.

You use a shift register like in the modified VI attached. A very similar example ships with LabVIEW. It's Fundamentals>Arrays and Clusters>Separate Array Values.
