I tried to edit many times, only to to plunge more deeply into the mire of HP's manuals. So, can any one to help me in this case?

Are you certain you've typed in the program exactly as it is given in the reference manual? I've tested this on a 50g with approximate mode both on and off, and in each case the program gave the expected results.

Note that the string in the list should actually have more spaces than is shown in your post, but that may simply be a result of the natural consolidation of spaces in HTML. If you look carefully in the manual you'll notice that there are 3 spaces, then a dash, 2 spaces, another dash, and then 4 spaces. This is important for the code to work properly, since it assumes a string in the "999-99-9999" format for this example to produce the expected results. Even without the extra spaces, though, the code should return something instead of producing the error you're seeing.
