What does this NASM statement mean?

mov [bx + LBA + 2-@], dl

The above is a piece of code of a program that NASM can compile. I don't understand what @ means, and of course I can't understand [bx + LBA + 2- @]. I have also read the NASM manual and have not seen this usage.

Maybe it ’s a typo. Should it be "$"?

It's not a mistake, because NASM can compile the program, and "@" and "$" are used in many places in the program.

@ Should be the address of a label

MASM / TASM can use @ 0, @ 1 as labels
@Have not tried, but in theory it should be possible
