Four subroutines are provided which access DECtapes on
TC-01 drives. In contrast to the routines provided by DEC,
these routines do not use the interrupt. If the user does not
require the use of the interrupt while doing DECtape I/O,
the use of these routines has several advantages:
l) They occupy less storage (106 [10] vs. 128 [10]
words); 2) The user need not establish page 0 linkages to
service the interrupt; 3) Other devices (such as the teletype)
will not interrupt the DECtape I/O. When, for instance,
transferring from paper tape to DECtape, one need not buffer
those characters which would have been read during DECtape
output.
