I beg to differ. That's disgusting code. 
It may work, but does not does what it suggest.

SS$_NORMAL is NOT a bitmask, it is a word value.
That only works because you know its value is 1.
If so, then IMHO it is better just write that: stat & 1
Or use  STS$M_SUCCESS as mentioned earlier,
Or use a 16-bit-word-compare.

fwiw,
