Are you working on your own compiler or you want to use such "backpatch
mechanism" in some language like C or Ada? For the first case, check out


"Compilers: Principles, Techniques, and Tools" A. Aho, R. Sethi and J. Ullman.


Page 500.


For the later case, you still need the above book and a copy of the compiler
source codes.
