Re: What is the execution flow of this file

[Laura]

Thanks @rocuinneagain for taking a look at my lengthy question! Let’s say we examine the flow this way:

1. information is generated by feedhandler fh.q (https://github.com/kxcontrib/websocket/blob/master/AppendixB/fh.q)
2. information is passed to tickerplant subpub.q (https://github.com/kxcontrib/websocket/blob/master/AppendixB/pubsub.q) (please correct me if this is not a tickerplant)
3. information is received by a JavaScript-based subscriber (https://github.com/kxcontrib/websocket/blob/master/AppendixB/websockets.js) In this particular example, I understand that information is randomly generated by fh.q; and fh.q interact with pubsub.q via these two function calls (https://github.com/kxcontrib/websocket/blob/ad2f0b268afaee1fc5f4dda2fc2467440c7e2f0c/AppendixB/fh.q#L18-L19) .

   My confusion starts here: in lines 18 and 19 of fh.q, `upd is an alias to insert; `quote and `trade are table names, and the rest are parameters randomly generated–so which line in pubsub.q will be invoked when these two function calls are made (please correct me if the term “function call” is inaccurate)?

    

   Thanks!
