What actually is the console in the case of tick, and why do we need to output l::0(`.u.ld;d) to it?

I have searched online and the console appears to be a place where you can input commands and view outputs, is this the command line? What is the console in the case of tick?

Secondly why do we output .u.ld[d] to the console using the permanent handle 0, what is the consequence of this?

Hi Mannix,

This piece of code is simply evaluating the function .u.ld with d as the input in the current process and returning the result.

In this case it’s preparing the tp log and setting the counters.

This link details the 0 handle, though I think you may have already been looking at this:
