; autoinit if you ever reference DiceCache.library
;
; (c)Copyright 1990, Matthew Dillon, All Rights Reserved
;
; can't use pc-relative between different code sections
; and cannot put string in autoinit section!
;
; As with the ARexx support, this does not abort
; if the library cannot be found. Furthermore,
; this routine only opens the library if it
; already exists (i.e. cache explicitly turned on)
