Usual nonsense: replying to my own postings:
The problem lies in my relying on put (KOUNT * 10) into LYNE
to supply me with continuous line numbers for my listField, now sorted out:
on mouseUp
put empty into fld "f1"
put 0.1 into KOUNT
put 1 into LYNE
repeat until KOUNT > 12.6
put ( ( ((sin (KOUNT)) * (cos (KOUNT)) ) * 300) + 400) into LR
put ((((cos (KOUNT)) ) * 300) +400) into TB
put (LR & "," & TB) into line LYNE of fld "f1"
add 0.1 to KOUNT
add 1 to LYNE
end repeat
set the points of grc "c1" to fld "f1"
end mouseUp
The IDE did not help with its cryptic message.

Of course part of this could be the problem that my initial curve
generation script leaves empty lines in
the listField that contains the points of the curve.

So I have a graphic object generated like this:
on mouseUp
put empty into fld "f1"
put 0.1 into KOUNT
repeat until KOUNT > 12.6
put (KOUNT * 10) into LYNE
put ( ( ((sin (KOUNT)) * (cos (KOUNT)) ) * 300) + 400) into LR
put ((((cos (KOUNT)) ) * 300) +400) into TB
put (LR & "," & TB) into line LYNE of fld "f1"
add 0.1 to KOUNT
end repeat
set the points of grc "c1" to fld "f1"
end mouseUp
(where grc "c1" is a pre-existing graphic)
and a button containing this:
on mouseUp
move grc "g1" to the points of grc "c1" in 10 seconds
end mouseUp
and all should be fine, but it isn't, because on attempted execution
of the button I get this:
"button "GO": execution error at line 2 (move: end point is not a
point), char 21".
All very mysterious, Richmond.
P.S. Before Mark, Jacque or Richard try it; there is a comma before
my name!
