WAITDEAD [ expression ]

   Synopsis:
      Pauses execution until the character's life status is 'dead'

   Notes:
      The Status task recognises four states of being for the character:
         "alive", "sleep", "passout" and "dead". Whenever the character is not
         asleep, passed out or dead, they're considered alive.
      The expression is a timeout measured in seconds. If specified, the script
         gives up waiting after that period and resumes execution.
         
      WAITDEAD relies on the Status task to supply the character's current life
         status. If the Status task is not running, the Axbasic script pauses
         pauses briefly and resumes execution on the next task loop.
      If the Status task doesn't know about the character's status, it assumes
         that the character is alive.
      See also the help for WAITALIVE, WAITSLEEP and WAITPASSOUT.

   Requires:
      If the script is not being run as a task, the WAITDEAD statement is
         ignored (and no error message is generated). Execution continues with
         the next statement.
         
   Examples:
      WAITDEAD
      WAITDEAD 100
