No background in painted rect

[mail at richard-hillen.de]

Hello list,

now I wanted to paint a rect filled with Color.
So i wrote:

..
  choose rectangle tool
  
  put 100& "," & 100 into LinksOben
  put 200 & "," & 50 into RechtsUnten
  put 200,50,100 into RGB_Color
  set the brushcolor to RGB_Color
  set the pencolor to RGB_Color --für den Rand
  drag from LinksOben to RechtsUnten
  
  choose browse tool
..

I got a rectangle, whose boprder was colored, but filled with no Color or
white, don´t know.

Hereafter I clicked on the polygon tool in the tools pallette and choosed
the rect tool .

I started my script again and now the rect was filled!

What property of which object has to be set?

May you help again? Thank You!

Richard.

P.S. I would like to find a help: How to paint graphic or painted
objects?
Do you know, where to find?
