Try running this self-explanatory Pascal program through pxp:
------------
program fred(output);
{ Guess what - BSD 4.2 pxp prints comments thus:
printf(commenttext);
so guess what happens when it encounters
a %% sign, especially one followed by *
}
{ The following comment contains %%x and %%*x }
{ %x %*x }
begin
null
end.
------------
I don't know if it's fixed in 4.3 (I doubt it,
only deranged students ever use comments, particularly
with any punctuation :-))
