Thank you very much for your answer to my issue.
Unfortunately, there are some problems with your suggestion.
First, the variable "varG" was meant to be a global variable accessed on rare occaisions of the execution in func and therefore needs to be accesed through the MainEvatuate[] function.
Second, changing the rank of the arguments is not an option for my calculations as i use the "listable" attribute to transfer non-tensor lists to the C library. (For example, the 5th argument would not be a tensor of depth 3, but a nested list of max depth 3.)
My best solution to the problem so far is to change the order of the arguments so that the higher depth elements (for listable mapping) are at the end of the argument chain.
