Jens, YES

This is one of the very great improvements of KiXtart,

If you use UBound() on a not defined variable or a variable that is not declared as as Array it will always return -1

This in combination with the automatic typecasting in KiXtart makes it easy to write very short code.

You don't have to write code to check the vartype of the variable in question (is it an array) before using it !!

Another note:
Don't be afraid of using the ReDim statement, it is very fast, so don't overdimension your arrays. Just ReDim them as needeed.

Third note:
Build in ASCan() funktion is also very fast!
