DECtape Duplicate (552)
5,8-22

Jim Miller, Dow Badische, Freeport, Texas

A DECtape routine for the PDP-5 to transfer all of one reel
(transport1) to another (transport 2). Occupies one page of
memory beginning at 7400. The last page of memory is not
used during the operation of the program; however, the
memory from 1 to 7436 is used to set the DECtape reels in
the proper starting attitude and is then destroyed during
duplication. Duplication will commence after which both
reels will rewind. Parity error will cause the program to halt
with 0040 in the accumulator.
