I have this piece of assembly:

.text:0041B322 xor     eax, eax
.text:0041B324 mov     al, byte ptr [ebp+v13]
.text:0041B327 cmp     eax, 1
.text:0041B32A jz      loc_41B37D
.text:0041B330 xor     eax, eax
.text:0041B332 mov     al, byte ptr [ebp+v13]

I would like to know what exactly is loc_41B37D in this context? I believe this means local piece of code. So it would be a label pointing to some address in memory. But I coudn't find any definition for this online. Can you link me some useful resource for this? Documentation maybe?

    loc = location it is the address where the jz jumps on condition true it is 0x56 bytes below the ip address of jz

"jz" is a conditional jump. Explanation HERE.

"loc" stands for location.

jz loc_41B37D means if the zero flag was set to 1, jump to location 41B37D.

Reading HERE would also help.
