RKD_WORD_WRAP with string input
I need to split a string with RKD_WORD_WRAP, but it seems it takes only chars as input, so I would like to do this: create a char variable dynamically as long as the string in input and then pass it to the RKD_WORD_WRAP. Can anybody please tell me how can I do it? I think I should use field symbol but I don't know them very much.
Thanks in advance.
