So the return value of TCLWS is for me:

This is the concatenated data of all fields.
Only within the beginning, the values are different.

I close my analysis so far.

Eventually, Gerald may shed more light on his comment what is exactly missing and going wrong here. And what would be the correct output ;-)

Thank you,
