Hi, Jacek, I'm far away from my linux box and I'm just passing by to
remember that there is a 24 continuation limit.

Here is an invalid operation because it has 26 continuations:
x = _
3 _
+ 3 _
+ 3 _
+ 3 _
+ 3 - _
3 + _
3 _
+ 3 _
+ 3 _
+ 3 _
+ 3 _
+ 3 _
+ 3 _
+ 3 _
+ 3 _
+ 3 _
+ 3 _
+ 3 _
+ 3 _
+ 3 _
+ 3 _
+ 3 _
+ 3 _
+ 3 _
+ 3 _
+ 3

And this is another test that must pass too (there is no new operand
after the last _ ) :
x = _
3 _
+ 3 _
+ 3 _
+ 3 _

As I said I can't test in wine but maybe you will find this information useful.

Best wishes,
Bruno

I've tested it and that doesn't seem to be true.

This will work only if the next line is empty (exactly like my 
implementation does).

You're right, in a vbs file the limit does not exist, it looks like to
be a Visual Basic 6 editor limit. Sorry for the noise.
