IBM Signal Processing - Status Vector

As expressions are processed it is possible that various kinds of arithmetic or logical exceptions can occur (eg. LOG(0.0) or result of the LLE function).

To deal with these situations and try and obtain some form of result vector JETDSP maintains a status vector with length equal to that of the common timebase. When an exception occurs the appropriate element of this vector becomes "set".

When building the final result vector elements whose corresponding status vector elements are set are skipped.

Thus the length of the generated signal may sometimes be shorter than you would expect as invalid points have been omitted.
