Thanks for the link to Rick's introduction. I still have a question - if my
program gets its input from two json strings -
{"V": 10} and {"V" : 10.1}, and I need to sum up all the Vs - how can I do
it?
Perhaps, I would have to suppress the . reader macro before calling
parseJson and then do a pass to normalize the numbers?
