That's the '@' thing I was talking about making a doc patch for. I then realized that I didn't understand it well enough to explain it! The little I grok is that a '@' in the assembly gets replaced by the value of $op_pc. Jako does stuff like: set I31, [ printit - @ - 3 ] For function calls. As I thought about documenting '@' I realized I had no idea what those braces are for... Seems to me whoever put in this hack should be the one to document it. -sam
