Outstanding solution. Thanks!

I found two quirky bugs with this procedure (I'm using XyIII+ currently):
(1) if I am already at the top of the file, alt-up will put the cursor on
the second paragraph; this creates an oscillating cursor. (2) if the
paragraphs are separated by two carriage returns, and the cursor is
located on the second , the result of alt-up will be to put the
cursor on the *following* paragraph.

The following seems to do the trick (in XPL III+):

®SX01,®CP¯¯BC seb ||XC ®if®er¯¯TF ®gl2¯®ei¯NP ®if®CP¯>=®PV01¯¯PP
®ei¯®lb2¯
              ....................     ..      
.....

The changes are under-dotted. The first change is to test for an error
after seb. If an error occurs, the cursor is already in the first
paragraph of the file. So I go ahead and TF, then escape the rest of the
program by using  and . The second change is to change the
comparison between CP and PV01 from == to >= . The "greater than or equal
to" comparison covers situations where the resulting CP is greater than
the starting CP, such as when the starting CP was on the second  in a
paragraph break.

My cursor is getting happier by the moment.
