Hello,

imagine the little program:

pro problem
read,mytagname,prompt="Enter Tagname: "
read,myvalue,prompt="This into it: "

mystruct=create_struct([mytagname,'test'],[myvalue,myvalue])

; this is easy and works
print,mystruct.test

; but how to get the myvalue via the first tagname?
print,mystruct.????

; ok, i can fetch it via tag_names:
thetagis=tag_names(mystruct)
thetagis=thetagis(0)

print,thetagis

; and my main problem is: how to set the unknown tag?

mystruct.???='THE NEW VALUE'

end

OK, any help needed...
