Thanks for the answer, but I think I expressed myself a bit unclearly.
The if-slope from the above code is an excerpt from an object called
"slide1". So far, I additionally had "slide2" with the exact same code
except for this fallowing line:

	if c.getattrib("ProbePos") = (i-1) then ProbeMask_SlideImage.Filename
= "probe.bmp"

After defining the slides with this code, I have:

run.slide1
run.slide2


My idea was that I should use:

run.slide1
[some code that changes one of the 100 images of slide1]
run.slide2

You are right, this does not make too much sense. It is an artifact
from another experiment when it made sense :-p
Nevertheless, this does not seem to be time-consuming.

Best,
Tobias
