$addtok is really quite easy aussiedags
$addtok(hi,there,32) = hi there
the first parameter is the text that will be added onto, the second is the text to add to the first parameter and the third parameter is the token to seperate the first and second parameters
a few examples
$addtok(this is,a test,32) = this is a test
$addtok(3,14,46) = 3.14
$addtok(hello,world,44) = hello,world
