Mirc Script

hi /prog/, i was wondering if any of you had knowledge on MirC script writing.

Essentially i need to write a bot who replies with a /play command to anyone who sends me a query/private message.

But i need a control variable who knows that this person already has talked to me so the /play is not executed ever again.

Please give me ideas /prog/ take your time.
