Re: Call a rpg program from a node script running on an external windows or linux server

[Brad Stone <bvstone@xxxxxxxxx>]

I just create an apache web instance and do a web call to the IBM i to get
the data (JSON preferably).  Write a little CGI program on the IBM i
accepting the request, build up the JSON, return it to the Node where it's
easily parsed.
