With a recent 2.7.1 (GO32V2) snapshot, it needs an explicit "if paramcount=0 then halt else assign(prr,paramstr(1))" for PCOM (etc). Though for some reason it doesn't fully write the output bytecode file unless an explicit "close(prr)" is done at the end. (I naively thought all files were closed and buffers flushed at every program exit.) Similarly for PINT, but then it seemed to somewhat work okay (though maybe a bug regarding set ranges). Not totally flawless, still needs work, but it's made good progress. Though I don't anticipate it passing all of Scott Moore's tests any time soon, but it's not an impossible dream anymore, thankfully. One of these days I'll have to compare closer (bytecode output) from a few test files (vs. GPC compiles' output).
