Hello Thomas Niederprüm,

But I also have a hard time remembering if | or << is higher precedence

man page of operator (man operator) will show the precedence.
<< is higher precendence than |

The point is that people should just use parenthesis when it's not
something that's obvious.

Also the more I think about it, writing "!par->com_seq & 0x1" is
nonsense.  If that's really what was intended then just say
"!par->com_seq".  I think it's a bug though and "!(par->com_seq & 0x1)"
is intended.
