1.0##^^INTRODUCTION\\
.BLANK 1
^^BOOTDX\\ IS A BOOTSTRAP PROGRAM DESIGNED TO LOAD OR DUMP PROGRAMS
FROM THE ^P^D^P-10 INTO THE ^P^D^P-8^A IN THE ^D^X-10.
^THE TWO MAIN FUNCTIONS OF ^^BOOTDX\\ ARE:
.BLANK 1
.LEFT MARGIN 9
.INDENT -4
1.##^LOADING A PROGRAM INTO ^P^D^P-8 MEMORY FROM A ^P^D^P-10 DISK
FILE OR THE ^P^D^P-10 PAPER TAPE READER.
.BLANK 1
^WARNING:  ^^BOOTDX\\  READS ^^ONLY\\ IMAGE MODE ^P^D^P-8 FILES.
.BLANK 1
.INDENT -4
2.##^DUMPING ^P^D^P-8 MEMORY INTO A ^P^D^P-10 DISK FILE, CREATING
AN ^^ASCII\\ LISTING OF THE CONTENTS OF THE ^P^D^P-8 SUITABLE FOR
LISTING ON A LINE PRINTER.
.BLANK 1
.LEFT MARGIN 0
^^BOOTDX\\ RUNS IN ^^USER\\ MODE UNDER A ^^DEC\\SYSTEM-10
TIMESHARING SYSTEM.  ^IT REQUIRES A MINIMUM OF 2^K OF MEMORY BUT EXPANDS
FOR ^I^O BUFFERS.
^^BOOTDX\\ DOES ^I^O INSTRUCTIONS DIRECT TO THE ^D^X10 HARDWARE.  ^FOR
THIS TO WORK, THE ^^BOOTDX\\ JOB MUST HAVE PRIVILEGES FOR THE
^^TRPSET\\ FUNCTION OF THE TIMESHARING SYSTEM.
