Queing TC01/TU55 DECtape Routines

8-393

James Crapuchettes, Stanford Electronics Labs, Stanford,

California

These routines, which are a much modified version of DECOS-

FUBO (previously DEC-08-31U) provide the user with the

ability to read and write 128 words (one memory page) from/

onto standard 129 word DECtape blocks. Successive blocks

are transferred into/from successive 128 word areas of memory.

The routines will transfer into/from any memory field, will

begin searching in either forward or reverse direction for the

block at which the transfer will begin, and will queue one

read/write reguest to keep the DECtape in motion (and

transferring data) as continuously as possible.
