  Then i made some changes and it is worse than before.
  Declared variables now do not pass between .ini and .inc; worse a declared
variable gets reset to zero inside the .inc .

  Debug file "true" (no other name possible) shows that PN=0 !!
  Furthermore POVray barfs on undefined variable Ulong in Tank.inc .
  How can i fix this?
