GETWNUM

Purpose:

Returns the Window number of a Window.

GETWNUM(win)

win

Optional. Window reference. Defaults to the current Window.

An integer, the Window number of the Window.

getwnum(w3)

returns 3.

If Window 2 is the current Window:

getwnum - 1

returns 1.

eval(sprintf("deriv(W%d)", getwnum-1))

performs a derivative of Window 1.

wref = refwindow(w3);

n = getwnum(wref);

n == 3

GETWNUM is useful in SPL routines and command files where the current Window number may not be obvious.

See GETWINNAME to return a string that contains the symbolic or numeric name of the Window.
