  Trap handlers have their own static storage area,  this is one of the main
  reasons for using trap handlers instead of subroutine modules.  Register
  A6 points to this area in a trap handler, however the calling process's A6
  register's contents can be found on the top of the stack upon entry to a
  trap handler.

  Hope this helps.
