Passs the structure, then inside modify the field you need modified:

PRO update_value, input

input.test = 13

END

data = {test:2, str:'hello'}

update_value, data

print,data

end

Note: you can get very fancy if you want a general routine,
perhaps pass in the field name and use that string in an execute call,
or pass the field number you want to modify, and access the
structure like input.(0) = 2

cheers,
bob
