MyPens[j] := pencircle scaled ((2+j)*pt);
“pt” is just a multiplier variable in MetaPost. there is an
implied multiplication operation, but that only works in
bare-number cases. That is why you need
(2+j)*pt
The outer parentheses are to prevent MetaPost from interpreting
your line as
(pencircle scaled (2+j)) * pt;
Best wishes,
Taco
