Anyway to shorten this if statement?

[dayalsoap]

 if(tag == TAG_START | tag == TAG_VOTE | tag == TAG_VOTE_NO ........ etc etc)

A switch might be appropriate.

By the way, using || with short circuit evaluation may be better than using | here.

Not only that... it will behave differently too.

What are you trying to do?
Show code if you can.
