 This submission consists of 2 directories, MACSNVAX.DIR and HALFTONE.DIR.
HALFTONE.DIR is a program that converts grey-level images into halftones
(ie, only 1s and 0s). It then has several output options to display the
result on printers and sixel devices. MACSNVAX is a program that allows VMS
to emulate a Macintosh for the purpose of file transfer and storage.
Included within the MACSNVAX directory are useful Macintosh objects
including an original Macintosh application that allows re-definition
of the pre-defined pagesizes.
 HALFTONE has not appeared on previous tapes. MACSNVAX has appeared on
the Spring 85 tape, but ran only under VMS V3.x. All programs in this
submission run under VMS V4.1.
