ABSTRACT
JMP-Se If Test checks the PDP-15 to ensure that the JMP. instructi on can
be executed properly. The computer is held in a JMP to the current
location instruction for a definite time interval. If, during this interval,
the JMP instruction fails, the error will be indicated to the operator.
If the JMP instruction does not fai I, it is moved elsewhere and the check
is repeated. All memory locations not occupied by the program are tested.

REQUIREMENTS

Standard PDP-15 Computer

The program uses a II of 4K memory for the program (A a:, a tf.!', t (,nea.
The program occupies memory from location 07500 to 07751 (Hid teo. t',
all memory locations below 07500.
2.3

Preliminary Programs
Basic instruction tests

LOADING PROCEDURE

3. 1

Method
a.

Put HR I tape of program in reader (high speed if avai lable)

Set ADDRESS SWITCHES to 07500; the BANK MODE switch on a 1.

Depress and release KEY READ-IN

STARTING PROCEDURE

4.1

Control Switch Settings
The following is a table of accumu lator sw itch settings and their action on
the program:

AC SWITCH

SET AS

Action

Halt on error.
Don't halt on error.
Don't print errors.
. Print errors.
Ring bell on error.
Ring bell after N passes.
Loop on current location.
Don't loop on current location.
Repeat whole test (a II locations).
Don't repeat whole test.

o
1

N is an arbitrary number (initially 400 ) which is controlled by the LAW-N
instruction in location 07500 and may ~e changed at the operator1s discretion.
4.2

Starting Address
The starting address of the program is 07500.

4.3

Program and/or Operator Action
a.

Set ADDRESS SWITCHES to 07500

Set ACCUMULATOR SWITCHES to desired positions (see section 4.1).
Normal setting is 520000.

Depress I/O RESET.

Depress START.

OPERATING PROCEDURE

5.1

Operational Switch Settings
(see section 4. 1)

5.2

Subroutine Abstracts
(None)

5.3

Program and/or Operator Action
To put the program in the SCOPE mode, the ACCUMULATOR SWITCH
REGISTER should be set to 240000 (don't halt, don't print, bell after
N passes, loop on current location).
The length of time for the execution of a JMP. instruction is controlled
by the Teletype.

ERRORS
Unless AC switch 1 is a 1, all errors will be printed on the teleprinter.

6. 1

Error Halts and Description
There is only one error halt in the program at location 07602. This
error halt will occur if the JMP. instruction drops a bit and CAL's
out. The computer will halt in location 07546 if the whole test is
not repeated.

6.2

Error Recovery
If AC switch 0 is a 1, the computer will halt on an error. To recover
and repeat the failure, reset AC switches 0 to 3 as necessary (see
section 4.1) and then depress CONTINUE.
To test a particular location below 07500, store the address to be
tested in location 07744 (POI NT). Restart the program at location
07505 (HERE1+ 1) with AC switch 3 a 1.

6.3

Error Typeout Example
JMP . TEST
JMP AT CAL FROM
001234

001230

The above typeout shows that the JMP . at location 1234 dropped
bit 15 and CALed from location 1230.
7.

RESTRICTIONS

7. 1

Starting Restrictions
(None)

7.2

Operating Restrictions
(None)

MISCELLANEOUS

8. 1

Execution Time
Approximately 10 minutes to test from 0 to 07477 .

10.

PP.OGRAM DEscr~ IPTION

The first function that is performed is that of initial ization. A
register to count loops and a location to assure typeout of the
error message header are initialized.

Then a location in the program, which indicates where the
present J MP • is to be, is set to zero.

All of memory is then cleared, locations 1 and 21 are init'ialized and the JMP • instruction is formed and stored in the appropriate memory location.

The teleprinter is then ordered to print to set its flag. The
interrupt system is then turned on and control is transferred
to the JMP . instruction.

After the teleprinter flag is set, assum ing no error (see h.)
control is returned to the program via the program interrupt
facility. A check is made to see if the current JMP . should
be repeated (sw itch 3). If so, then the program returns to
c. except that memory is not cleared again.

If the current JMP • is not repeated, a check is made about
ringing the bell (switch 2) and then the number in the internal
JMP • pointer is incremented and checked to see that it is
not 1, 7, 21, or the first address in the program. If it is 1, 7,
or 21, it is incremented again. The program then returns to c.

After testing all memory locations, a check is made to see if
the test should be repeated (switch 4). If so, the program returns
to a. If not, the program ha Its.

If an error occurs, it is expected that the computer will CAL.
When this takes place, control is transferred to an error reporting
routine which turns off the interrupt facil ity, rings the bell
(if appropriate), prints the error (if appropriate), stops (if
appropriate) and returns to e.
