HOW TO

COMPLETE YOUR SPR FORM (DEC 1@44B-R373)

In order to provide effective service and maintain comprehensive f i l e s ,
it is essential that the influx of information received by Software
Communications be as accurate and complete as possible.

It is, therefore, extremely important that you include all relevant
information when you submit an SPR form.

The following three pages provide information on the steps to follow
when completing an SPR form. Your cooperation in this matter will
help expedite improved SPR service.

example

The following is offered to assist you when processing an SPR. All
blocks that are not numbered are for DEC use only. All numbered
blocks should be completed by the customer as described. Typed
input is recommended - if it can't be read, it can't be processed.
Each page attached should be numbered in the top right corner.
N = this cover sheet plus all the attached pages (terminal
printouts, line printer listings, etc.).

The customer should assign his record keeping number here. This
number will be referenced on the acknowledgement of receipt sent
out by Software Communications, thus eliminating confusion.
Name of the person at the site responsible for SPR activity.
Further communications regarding the SPR will be directed to
this individual.
Name of the submitting organization.
Address of the submitting organization.
Telephone number of person's name appearing in block 3 .
The date sent to the DEC field office responsible for your
SPR activity.
NOTE:

The month should be written using letters rather
than numbers, i.e., OCT.

Processor type.

If the situation being reported is related to a specific system
device, list the DEC option code here.
Amount of core on your system.
The customer should check the block most appropriate to the
situation.
Any information related to your system configuration that may
help in diagnosing the problem.
The Software Product Component in which you feel the problem
resides and its version number.
EXAMPLE:

MACRO,

V5A

The Software Product Name and version number.
EXAMPLE:

DOS-11, Vp/8.p/2

(15) If the problem relates to a DEC Document, insert the DEC
Document number and the page(s) referred to.

(16) Check the appropriate box. Attempt to reduce the problem
to a simple test case. If you cannot, include all programs
and data in some machine readable form.
(17)* State the situation you wish to make DEC aware of.
-----ONLY ONE PER SPR FORM----(18)* If a patch or way around the situation exists, include it
here.

If additional space is required to present this information,
USE A SECOND SPR FORM.
Forward all four copies of the SPR to the DEC office responsible for your SPR activity.

Software (hardware) problem with EAE (KE12)

PROBLEM:
The instructions CLA (76j31) and NMI (7411) are defined as
being micro programmable, but due to a hardware problem
they do not function properly when micro programmed.
SOLUTION :

Therefore, the instructions CLA and NMI should be used as
two separate instructions. No correction is planned for
the hardware.

CATACAL
Patch to correct time VS. amplitude err,or

PROBLEM:
A problem exists concerning incorrect amplitude scaling
in the averager as a function of sample rate.
CATACAL uses "window" or "boxcar" averaging and scales
down the sum by an appropriate power of two determined
by sample rate. However, in the region of 1$Y to 1 points
per second, there is a problem which 3ffectively divides
the data by an extra power of two so the results are halfsized.
SOLUTION:
This is corrected by assembling the following patch and
doing an ADD BINARY under DIAL-MS to current CATACAL
binary.

Two other small corrections are also included in the
patch:
1.

Removing Y axis cursor "fudge" factor.

A small change to integer float routine to guarantee
that the entire FAC and overflow word are correctly
set up before normalizing it.

LAP6-DIAL-MS
Two bootstraps to load LAP6-DIAL-MS directly from the disk

The following two bootstraps should be used to load LAP6DIAL-MS directly from the disk (RFg8 or RKg8). Each
bootstrap when assembled, will yield one block of binary
! of the respective disk via
that must be moved to block J
PDP-12 PIP. The following instructions should be followed
to assemble the bootstrap needed:
1.

Type up the program via LAP6-DIAL EDITOR

+ZE

(zero binary work area)

+AS

(assemble program)

+SB

(save binary of program)

+DX

(note where the one block of binary is saved)

+PIP*(load PIP and transfer the one block of binary to
RlP (disk j l ) , block g)

Toggle in the two or four word bootstrap and LAPG-DIAL-MS
will start up.

*After the PIP transfer, the user should create an index
entry (via PDP-12 TED) in the DIAL index so that DIAL will
not save a file over this binary.
The procedure above assumes that the disk has been initialized
See LAP6-DIAL Manual, DEC-12-SE2D-D; Appendix A, section A.3.

DIAL-MS
Patch to force LINCtape to be the system device

PROBLEM:
There are a number of occasions when it is desirable that
DIAL-MS does not use a disk as the system device, even
though one is present on the system. Among these instances
are the following cases:
1.

Using the FPP Assembler on a system with one
DF-32 disk: the Assembler requires DIAL-MA,
but also requires that if DF-32's are used as
the system device, at least two must be present.

Using FOCAL-12 under these same circumstances.

Initializing a tape on a system with an inoperable
or malfunctioning disk.

Starting up DIAL-MS on a system in which the
disk must not be overwritten, e.g., in a CL-12
or PS/12 situation.

SOLUTION:
The following patch to the DIAL-MS system tape solves this
problem by allowing sense switch (a to affect the choice
of a system device. If SS (a is in the (a position, DIAL-MS
is initialized in the same manner as it currently is. If
SS (a is in the 1 position at the time of initialization,
however, LINCtape will be chosen as the system device
regardless of what disks are present on the system.

disk whenever the disk is initialized, i.e. LS=87$31; RS=7318;
I/O Preset; DO; Start 28. This will result in block
478 to 477, usually reserved for file area, to be overlaid
by whatever is contained in blocks 478 to 477 on the
LINCtape.

The following patch will correct this problem.

problems if he encounters the following situation:

/THIS IS THE LAST LINE

BLOCK

Assume there are four spaces after 1 in 181. By
moving the cursor back using knob 3 to anywhere on
the line and pressing a return, line 4848 up to the
cursor will be stored (written) onto block 478.
The same procedure will work if you are at line
7 7 7 7 , except the next thing viewed on the scope
is line 1 and the entire working area is destroyed.
SOLUTION:
DO

- turn the cursor back and strike a carriage return
in the middle of a line whenever there is a lgg block

Problem with the availability of relays

PROBLEM:
The LAP6-DIAL V2 EDITOR checks the availability of the
relays, to determine whether to use the analog potientiometers
in the Editor.
ALTERNATE SOLUTION:
To get around this, the following patch should be used:
1. Load block 312 into core via 8788 8312; I/O preset: DO
2.

Change LINC location 4846 from 7658 to 7288

Rewrite back onto tape block 312 via 8784

Additional notes on Automatic Mode

The following information on the automatic mode should be
inserted in the MASH User's Manual (DEC-12-SQ2A-D), as the
third paragraph on page 16.
If G is typed again, automatic mode initiates a series of
scans that last until the chromatograph run is complete.
Pressing one of the right switches on the console terminates
scanning and returns the program to the TIC VS. Time plot.
