This program allows quick, controlled data-block transfers

between the PDP-8 and DECtape. It reads, writes and

searches in minimum time (interrupt mode), requires minimum

space (overlay-with last page BIN, RIM, DECSYS Loaders)

and occupies only two blocks on tape (block 0 = System,

block 1 = Return-System). It is protected against destruction

and gives, after the transfer, the status levels for testing

purposes. It is usuable as a Switch Register controlled program

or as a subroutine with or without interrupt, giving

the possibility of quick data storage, program shuffling and

overlay technique with PDP-8 and DECtape.
