THe same is true for .arg directives. I tried to solve this once, but it didn't work out. Not sure whether I tried hard enough. In any case, I'm working on a complete new bison file for PIR. This one removes all these kinds of "bugs". I added the bison/flex files under compilers/pirc/new/ I'm not sure to what extent it's possible to change imcc.y or maybe it's better to do a rewrite of it (by adding the semantic actions to the new version). A rewrite would also allow us to refactor the lexer, so that it no longer uses globals (I think IMCC has too many globals currently to be reentrant). I'm looking forward to PDD19 being reviewed/approved, so that we have a "final" definition of PIR. A number of issues need to be resolved first. kjs
