About programming 8051

Hello,
I am right now programming in assemblor and I would like to be able to save in a variable the PC of a label.
I would like also to jump at a label, having in a variable the PC of this label.

thanks a lot

For computed jumps, use the JMP @DPTR+A opcode.

To save a label address, you need a copy of it somewhere, i.e. a set of

db BYTE0(label) db BYTE1(label)

somewhere in your code, so you can copy them to where they're needed.
