3.0 PROGRAM PROCEDURES
3.1 LOADING PROCEDURE
PAPER TAPE - HARDWARE READ-IN (READER DEVICE CODE 104)
DECTAPE - LOAD WITH DIAMON (DECTAPE DEVICE CODE 320)
3.2 STARTING PROCEDURE
STAND-ALONE STARTING ADDRESS IS 30000.
IF THE DIAGNOSTIC FAILS TO START CORRECTLY TRY STARTING AT THE
FIRST TEST INSTEAD OF AT THE BEGINNING OF THE CONTROL SEQUENCE.
(SEE LISTING).
3.3 OPERATING PROCEDURE
ONCE STARTED THE PROGRAM WILL CYCLE CONTINUALLY UNTIL STOPPED
OR AN ERROR OCCURS.
4.0 ERRORS
ERRORS ARE IN THE FORM OF HALT INSTRUCTIONS. THE LISTING
SHOULD BE CONSULTED TO DETERMINE THE CAUSE OF THE ERROR. A
NO OPERATION (JUMP) INSTRUCTION FOLLOWS EACH HALT. THIS
MAY BE USEFUL IN CONSTRUCTING A SCOPE LOOP TO CYCLE ON THE
FAILING INSTRUCTION.
5.0 ITERATION COUNTER
THE ITERATION COUNT OF THE PROGRAM IS DISPLAYED IN THE MEM-
ORY INDICATORS (MI). THIS COUNT IS A DECREMENTING COUNT AND
INITIALLY STARTS AT -1 IN STAND-ALONE OPERATION.
6.0 CYCLE TIME
THE CYCLE TIME OF THE PROGRAM IS IN THE MILLISECOND RANGE AND
IS THEREFORE SUITABLE FOR TAKING MARGINS, VIBRATION TESTS, ETC.

7.0 OPERATIONAL VARIATIONS
A. DIAGNOSTIC MONITOR
THE PROGRAM IS USABLE WITH THE DIAGNOSTIC MONITOR TO PRO-
VIDE RELIABILITY TESTS, ACCEPTANCE TESTS, AND/OR TO PRO-
VIDE A QUICK METHOD OF ISOLATION OF A FAULT TO A PARTICULAR
AREA OF THE PROCESSOR. CERTAIN PROCEDURES ARE USED WHEN
THE PROGRAM IS USED IN THIS MANNER. THEY ARE:
1. THE DIAGNOSTIC MONITOR TRANSFERS CONTROL TO THE PRO-
GRAM AND STARTS IT AT LOCATION 30002.
2. MONCTL - LOCATION 30043 IS USED AS THE DIAGNOSTIC MON-
ITOR CONTROL FLAG WORD.
B. USER MODE
THE PROGRAM WILL OPERATE IN USER MODE AND AS SUCH PROVIDES
ASSURANCE THAT THE PROCESSOR IS PERFORMING ALL FUNCTIONS
CORRECTLY. USER MODE STARTING ADDRESS IS 30000.
C. SYSTEM EXERCISER
STARTING ADDRESS IS 30003. NO DATA SWITCHES ARE USED BY
THIS PROGRAM.
