What is the poke to turn the first line in a program to like 0 and back?

a man named ANTHONY T. ORESTEEN discribed it like that:

POKE 16510,0

this makes first lane number 0, can´t be edited. use for copyright
notice. to hide LISTing use the following: - ENTER III REM ad" than POKE
16514,118 and POKE 16515,118; LISTing is gone

Depends on what Sinclair computer :)

For the Speccy it's POKE 23756,0 assuming you have no IF 1 attached.
No prizes for guessing what POKE turns it back again :)

Oh, well, in that case ignore my last message.

We used to shove loads of dummy chars in that line and then overwrite them
with machine code routines as well of course, but you really did then have
to make the number uneditable or accidental editing udid all your work.

Ultimate games always used to use this to prevent you changing the loader.
Ratbags. And it was all one long line as well, which you had to re-poke and
then shift-8 all the way through just to add POKE 44786,0 right at the
bloody end.

Well its actualy for the P.A.W.S. program so i can alter the loader to load
from the plus d and not from tape.
No interface 1 is used.

Wow, that is quite old discussion here.
I remember finding out this poke 23756,0 by myself by running poke in for cycle and rebooting (frequently) when system was corrupted.
I was so happy when I finally saw the 0 line. At the time there was nobody to share this finding with :D (no web, no email)
It worked on Didactic Gama (ZX Spectrum compatible machine)
