Color in the G2D.Ellipse routine is the 6th argument, not 5th!
So watchout for argument matches between my draw subs and QBJS substitutes with G2D.drawsub

Make sure array indexes are integers, QBJS does not fix floaters like QB64.

You can fix it by "Fix"ing or "_Round"ing the parameters sent to PSet on line 57: |

You can fix it by "Fix"ing or "_Round"ing the parameters sent to PSet on line 57: Yes fix() or int() works thanks! dboxSo Point() demands integers for arguments like array indexes And that reminds me, _RGB32() needs >= 0 and <=255 |

At the top before any line of code:
$IF WEB Then...
eg when using Circle Fill sub
Also something about Chr$ or Asc of an K$ = Inkey$ is off, Len(K$) works.
