Re: What exactly does .u.end do?

Hi,

1-3) Correct.

4) yes this is a date, you will notice end is called from endofday function in tick.q, which is called when the date rolls, checked on the timer.

endofday:{end d;d+:1;if[l;hclose l;l::0(`.u.ld;d)]};

Where d is the current date the tp is running.

.u.end will be an EOD function on the subscriber, commonly an RDB an example below from r.q:

/ end of day: save, clear, hdb reload
.u.end:{t:tables`.;t@:where `g=attr each t@:`sym;.Q.hdpf[`$":",.u.x 1;`:.;x;`sym];@[;`sym;`g#] each t;}

Hope that helps.
