Hello,
no, unfortunately,
even internally, filled circles are done using a fillpoly...

Thank cyrille
using fillpoly has given me an idea
Could it be something like this?
Code:
EXPORT fillcircle()
BEGIN
LOCAL COORD:={};
dimgrob_p(G1, 200,200,RGB(255,255,255,128));
FOR A FROM 1 TO 90 DO
COORD(A,1):=99+99*COS(4*A);
COORD(A,2):=99+99*sin(4*A);
end;
FILLPOLY_P(G1,COORD,#FF, 128);
RECT();
BLIT_P(G1);
WAIT(-1);

There is also this program from MacBernick from a few months ago: http://www.omnimaga.org/hp-prime/fast-filled-circles-routine/?action=dlattach;attach=16703

I don't know how to get rid of the Select program prompt at the beginning, though.
The program looks somewhat fast and if you want you can modify it so that the circles are translucent.
I'll try your program as well.
