Another option is to use the switch statement. So if you just want to see if "X", "Y", or "Z" are in a string, this would do the trick:

switch -glob $var {
  "*A*" -
  "*B*" -
  "*C*" {
     match found
  }
  default {
     no match found
  }
}

This will perform a bit faster than a comparable regular expression or if/elseif statements.
