One thing I didn't explain is that I used a Variant for the auto
String-Integer coercion (between others).
Thank you for your explanations, that is exactly what I supposed it
does... once I get the error string which is very explicit in this case.
The real object of the original mail was to flag this "strange behavior"
- for me - ...
I already use Variant for other things and Variant is good.
And the original idea waas to have a better styled example to pass data
to an array (to create PolyGon).
BTW: the "start filling Array at position 1" have to be explained in the
Language Reference (documentation). I didn't ask the explanation why,
but a simple sentence telling that "it works that way".
I will follow your suggestion

This fails for two reasons. First, you can't call Split on a variant (and
there is no need for this to be a variant; you're only storing a string in it,
so you should declare it as a string). Second, Split returns an array of
strings, not an array of integers.
// Test #2 (fails too)
TriOne = Split(TriangleOne,",")
This one correctly calls Split, but fails for reason two: the result is
String(), and you're trying to stuff it into Integer(), which is a type
mismatch.
To split a string and then convert that into an array of integers, you could
use the SplitToInt function in the StringUtils module:
TriOne = SplitToInt( TriangleOne, "," )
But even easier might be to simply use the built-in Array function:
TriOne = Array( 0, 5,5,25,5,15,25 )
Note that I have to insert an extra number (0) because DrawPolygon expects a
1-based array for odd historical reasons.
Also note, with any of these, that it doesn't matter how big you dimension
TriOne in its Dim statement; you're going to throw out that array and replace
it with the result of SplitToInt or Array anyway. So just declare it as: Dim
TriOne() as Integer.
