Sure guys thanks for the support.
I need to create an register a table based on the content of a DS<>, the
point is that within the content I need to parse it somehow and get the
part which is the values and the headers. I already tried to create a DS
and register the new DS as table with headers and values catch within the
anonymous function.
However the anonymous function can not reach my env and tenv. therefore I
can yes create the DS with values but I need to store the headers to be
accessed out from the anonymous and register the tenv with the content of
the new DS and the headers from my variable. I bit weird maybe I know but
this is what we need :).
