Re: Arguments of .Q.hdpf

[Laura]

The complete call in the white paper is .Q.hdpf[`$":",.u.x 1;`:.;x;`sym].

The first argument is `$":",.u.x 1. From the .Q.hdpf documentation we see the first argument is a port for the HDB. It looks like .u.x. 1 is that as a string; for example "localhost:5002".

`$":", prefixes a colon and casts to symbol, creating a handle.
