I have an application that defines a data structure using the STRUCTURE stage. I can define the structure and read the values of individual members without difficulty – there’s a nice example of how to do it in the docs. What I’m trying to do is reference a field of the structure for update with new data. I understand that using PICK with the MEMBER operand lets me filter the records down to the one I want, but nothing seems to let me update the value.
Questions: 1. Is this possible? It would seem to be something that would fit in SPECS, but I can’t find any obvious keyword or combination of keywords that would allow me to specify the structure.field name as an output target. 2. If not, would keeping a reference list of the field names and column ranges be the most straightforward approach? I think I can construct the SPECS magic I need, but if there’s a better way, please enlighten me. I’m targeting the last runtime library version and the 7.1 version of pipes. All advice gladly accepted.
