Whoops, sorry about the top post - gmail conveniently hides it.
Never seen it in assembly, maybe I got too late to the assembly game (around 1982), all assemblers I have used had proper labels (or maybe they supported it but noone I interacted with used them - thank God!)
Anyhow, I prefer labels to be named according to their function in the loop because even I who has advocated goto usage in C for a long time in the workplace find them pretty much unneeded nowadays and obscuring flow.
