Alan,
OK. so readfile was easy. I think I missed a trick there. Anyway...
The big difference between Yahoo and the BLS is that the BLS returns a
JSON format. Any suggestions on parsing a JSON result string? Will join
do that?
Not easily. In fact, I had to use JSON objects some time ago and I used
perl for that, but we could probably introduce a hansl primitive for
converting bundles from/to JSON objects. The only missing piece of the
puzzle would be that we don't have a generic array type. Allin and I
discussed the opportunity of introducing an "array" data type a few months
back. The problem is, it'll have to be for the next release.
In the meantime, would your job be doable via the existing hansl string
functions?
