Returns 1 if Window contains a saved series.
Optional. A Window, defaults to the current Window.
1 if the window contains a saved series, else 0.
W1: gnorm(1000, 1)
a = iswinds(w1);
b = iswinds(w2);
c = iswinds(w3);
Both a and c are 0 indicating the Window contains a derived series, i.e. a newly generated series or a series derived from an existing series. b == 1, indicating that W2 contain a series saved in a dataset.
ISWINDS checks if a Window exclusively contains a series saved in an existing dataset. The Window formula is parsed to check if the formula is in dataset.ver.series format.
See ISDSNAME to check if a string is in dataset.ver.series format.
