Dear All,

How do I turn a 5 by 2 data set into a single string?
The data set looks like this:

A B C D E
P Q R S T

the final result should be
"A B C D E P Q R S T"

    Hi wessel,

    just in case your problem has meanwhile not been solved, this process should do the trick.
    By rotating the dataset and re-executing your "merge"-loop the single string appears.

    Best regards,
