ABSTRACT
Details of computer programs and their operating instructions are
given for the processing of logbook-type data and associated analogue stress
signals into digital format. The logbook data is keypunched, edited and
formatted for subsequent merging with the analogue signal which has been
pro-cessed through an Analogue-to-Digital (AID) converter. Accumulation of
summary data during the processing is also output on to digital magnetic tape
which is then available for use in statistical analyses. A program for
re-trieval of selected data from the digital magnetic tape is included.

-I.. INTRODUCTION
Midship bending stress data from four dry-cargo ships, accumulated during an
eleven-year period ending in 1970 under Ship Structure Committee Project SR-153,
"Ship Response Statistics" were available as analogue signals recorded on magnetic
tape. Associated with these data were logbooks which contain hand-entry
data
relative to pertinent ship, sea and weather information. Subsequent to the
collec-tion of data, better techniques
became available for digital processing of data by high-speed computers, thus permitting easier and better access to the data for statistical purposes.
In Reference 1, the general method
was described which prepared and digitized the analogue signals and combined
them with the corresponding logbook information.
Further, demonstration examples were given of the retrieval of various items of data
and of presentation formats for use in statistical analyses. Although no statistical
analyses were intended as part of this project, ample evidence
was given of the
pos-sibilities available through the use of the detailed programs developed during the
project.
This report presents the details of the several computer programs which were
developed to handle, process, edit,
compact, retrieve and display the data original-ly recorded in analogue form (on magnetic tape)
and as hand-entry logbooks. Although
the program.s were specifically written to handle midship bending stress and related
data, they can be used with minor modifications to handle a broad variety of
ana-logue signals.
II. COMPUTER PROGRANS
To aid the reader, each of the several programs developed has been described
in a separate Appendix as shown on Table I. Thus, use of one or more of the programs
for other applications should be made more convenient. However, a short description
of the major programs is given here with the subroutine and peripheral programs
given only brief reference.
The logbook data were prepared as punched card input. The analogue
process-ing equipment utilized a perforated paper-tape input, thus a Logbook Pre-Processor
program was used to edit the punched-card
data and prepare the perforated paper tape. The paper tape also contained
operating instructions for the computer. These paper
tapes were then read into the
processor computer and stored for subsequent use and merging with the digitized stress signals.

-2-details for the Logbook Pre-Processor program and in Appendix B are given the
de-tails of the Logbook Paper-Tape Load program which reads and stores the logbook
data in the computer.
The main processing program (called Data Conversion and Analysis) operated in a real-time environment through the Real-Time Programmable Clock within the
computer. In Appendix C are given the details of the program, written in Assemoler
Language which permitted processing to be done at a rate increase factor up to 25 over the original recording rate (0.3 inch/second) without requiring starting and stopping of the analogue playback unit.
The practicality of processing and writing a complete digital data tape with-out errors (which would have necessitated considerable rerunning of much already completed and correct data) early indicated a requirement for the capability to edit and compact partially filled data tapes onto one essentially filled data tape.
A Summary Tape and Edit program (Appendix D) provides this capability and permits
certain editing options. For data retrieval to be used for statistical studies,
the computer read time could be shortened appreciably by reading only the pertinent
data and not reading the 12,000 pieces of raw data recorded for each interval. A
Final Summary Tape program (Appendix E) was written which allowed the complete sum-mary information for the 217 voyages to be recorded on two tapes.
The utilization of the data on the Final Summary Tapes required a program to
read the tapes and perform the comparisons or to select certain data. The
Para-metric Studies program (Appendix H) permits the reading of the tapes and provides
output of required information as punched cards, printout, or stored on magnetic
tape for further processing.
The programs or subroutine given in the remaining Appendices were used to list
data on the magnetic tape (Appendix G) and correct the relative wind computation
(Appendices F and I).
III. RESULTS
Use of the several computer programs given in the Appendices permitted the
processing of the analogue stress data and logbook information into digital form and
allowed selective retrieval of data for use in statistical studies. As a point of
reference, typical usage of the program can be used to determine approximate costs
for additional or similar use. The typical sequence of activities to process 100
intervals (and associated logbook information) and output to a Final Summary Tape consists of the following.
The keypunched logbook data are loaded onto perforated paper tape (using a
standard IBM 1130 computer with paper-tape punch). Approximately one hour of
com-puter time is required to list, edit and prepare the paper tape (including
verifica-tion printout). The paper tape is read into a PDP-8/I Computer and the data stored
on DECtape using approximately 30 minutes of computer processor time. To digitize
and process 100 intervals (originally recorded for approximately 32 minutes each
at 0.3 inch/minute) at a speed-up factor of 25, requires approximately 2 1/4 hours
of PDP-8/I computer time,
The preparation of a Final Summary Tape from several tapes is dependent on
several factors. The generation of a tape (equivalent to the full-bridge data tape
of approximately 7700 intervals from 15 data tapes) would require approximately
1 hour of IBM 360/65 computer time. It would require approximately 10 minutes to
run such a Final Suary Tape through the IBM 360/65 to retrieve the data from the
PARM program. However, judicious use of the program permits several studies to be
The details of the computer programs necessary to prepare and digitize
ana-logue and logbook data obtained during eleven years of acquiring midship bending
stress data from four dry-cargo vessels under Ship Structure Committee Project
SR-153, "Ship Response Statistics" are given.
In addition, the details are given of the program used to retrieve selected data and present the results in a form for statistical analysis.
While the programs were written for the specific application, only minor
modifications would be required to permit utilization on a wider variety of logbook-type data and recorded analogue signals.

LOGBOOK PREPROCESSOR PROGRAX
INTRODUCTION
This program was written to take the logbook data, which has been punched ou computer cards, and process it to output as a punched paper tape for subsequent merging with the analogue signal data to produce the digital magnetic tape of data.
Logbook data had been recordec in four slightly different formata during the
data acquisition projects. This program accepta data in any of the four formata
(as indicated on the header card) and converts to a standard format.
After completion of all logbook data preprocessing and during the production
runs of data, it was determined that there was an error in converting certain wind
direction data to the standard format Relative Wind. A subroutine was subsequently
written (see Appendix I) to correct the Relative Wind data at a later point in the
editing portion of the processing. While this subroutine could be incorporated
readily into the Logbook Preprocessor program to provide the correct information ou
the punched paper tapes (and eliminate the need for correction during the edit
process), it has not been incorporated into the program listing given herein. GENERAL DESCRIPTION
The program has been code named
VOYAGE and herein is referred to by that name
rather than the longer and more descriptive title.
VOYAGE reads logbook data in the form of header information (6 header cards),
interval information (2 cards for each interval) and voyage identification
informs-tion (2 cards for each voyage). The format of the input cards is shown in Table
A-I. The program prints the input cards, punches a paper tape from the information
and prints
an
image of the punched output according to the options specified by theoperator. The program allows for any combinatioa of the operations specified above
except printing of cards and printing the punched output simultaneously. The format
of the output (punched paper tape) is given in Table A-II.
The program reads six header cards and performs the required operations. It
then reads the nuthers of voyage and interval carda specified in the 3rd header
card, performing the required calculations and operations after each set of 2 cards
is read. As these cards are read, a check is made on Coluan 78 to determine the
presence of a voyage card. (Voyage Identification cards are identified by the
letter V in Coluni 78.) If a voyage card is out of order or missing, an
appropri-ate error message is typed.
There are four types of interval cards; formats A, B, C, and D. The formst
type is punched in the first interval card of each set. The program handles each
type differently, providing conversions and information reordering where required.

If the operator requests that the cards be listed on the printer, the
header cards will be listed first. Then the first card from each interval in a
voyage will be listed, while the second card from each interval is stored on
disk. When all interval cards for a voyage are read, the second card for each
interval will be printed followed by the two voyage cards.
An "End of Job" message on the console typewriter signals the successful completion of the run.
A listing of the program is given in Table Â-III and the flow chart is given in Figures A-1 and A-2.
SYSTEM REQUIREMENTS I
VOYAGE requires a ixdified version of the PAPTZ routine. This modif led
version is program No. 1130-03.440.6. However, this "ASCII PAPTZ" was modified
to provide for the specific requirements. These modifications consist of:
(1) Changing some entries in the conversion table to give the correct punched-paper-tape characters.
I (2) Changing the program to prevent the output of an EOR (End of record)
character following a 72 character group.
VOYAGE requires the 1130 Coamercial Subroutines VIII GET, PUT, WHOLE and
NZONE.
VOYAGE requires 100 sectors in the Fixed Area for its file, VFILE. The VOYAGE program is made up of two "Links", that is, two core loads.
The
first link, VOY, types the printing and punching option messages. It alsooperates on the six header cards. The second link, VOY1, performs the remainder
of the operations. Both links are stored in Core Image form, in order to reduce
execution time.

-15-APPENDIX B
LOGBOOK PAPER TAPE LOAD PROGRA}i
The logbook punched paper tape (in ASCII format as outputted by the Pro-processor program--see Appendix A) is used as input for the PDP-8/I computer
program "PAPT". The data on the punched paper tape is loaded on the PDP-/I
computer through the ASR-33 teletype. After being read into the computer,
the data is converted to EBCDIC (Extended Binary Coded Decimal Interchange Code)
to be consistent with the required magnetic tape format. After conversion, the
data is stored on DECtape for subsequent merging with the digitized record dur-ing the data processdur-ing phase.
The punched paper tape has the data formatted in DECtape blocks which
con-sist of l28i characters/blocks. The first 3 blocks (i.e., Header) on the paper
tape are utilized for the magnetic tape label and parameters needed for control
of the data processing phase. The format for the Header blocks is given in
Appendix A, Table A-II. The parameter used in the control of the data
acquisi-tion phase are the number of voyages to be written on each magnetic data tape, the number of original FM analogue tape passes for each voyage, the number of intervals in each pass of data, and a table giving the intervals which require special instructions; namely, the intervals that are long, tó be deleted, or have program halts.
After the Header blocks the Interval Logbook data is read in. These
consist of two blocks per interval. Four blocks are left blank after each logbook
interval. These are utilized by the data processing program for storage of
Interval Summary data (i.e., wave-induced peak-to-trough, RNS, and maximum peak-to-trough first-mode stresses, etc.).
The last two blocks in each voyage contain the Voyage Logbook data and are
handled in the same manner as the Interval Logbook Data. Again, four DECtape
blocks are left blank after each voyage for storage of Voyage
Siary data.
The program which accomplishes the above is listed in Table B-I. Figure
B-1 gives the flow chart of the program. The first 128 locations of the progr
contain parameters and the interrupt service routines. The interrupt system
al-lows for overlap (multi-processing).
Locations 2008 to contain the DECtape handler routine. This is a
standard routine supplied by Digital Equipment Corporation for reading from1 and writing onto, the DECtape unit.
The program starts at location 04008, the interrupt enable is turned off
and
the counters and data storage buffers are cleared and initialized. Thede-tailed procedure for loading the paper-Tape Load Program (PAPT) and execution of
-16-The Search subroutine searches for the Starting block on DECtap unit 3.
After the starting block has been found, the teletyps paper-tape feed switch
is set to STAr, and the paper tap. is read. The end of a block of data is
distinguished by the
special
character (c) "less than".Use
of the charactereliminates the need to zero fill blocks of paper tape to get 128 characters. By using the de-limiter, the program asstes it is the end of a block of data.
Since the teletype keyboard only reads 10 characters/sec.
considerable
unneces-sary reading of zeroes is e141n*ted, thus speeding the reading of paper tapes. As each character is read it is converted from ASCII to EBCDIC by the
subroutine RECODE. After the Header information (3 b locks) is read in, the
program uses the parameter given in the last two blocks of the papar-tape header to control the subsequent reading of the paper tape.
After the last voyage, logbook data is read
in
the prograa halts. TheSTART

-24-APPENDIX C
DATA CONVERSION AND ANALYSIS PROGRAN
INTRODUCTION
The processor program for digitizing and preparing digital library tapes of ship stresses and environmental data have been modified from that given in
Reference 2. Early in the processing phase it was determined that
sosie
modifi-cations to the program were needed in order to maintain good production schedule.
The type of data being digitized requires that the data conversion and
ana-lysis effort be operated in a
Real-Time
environment which is possible through theuse of the Real-Time Programmable Clock. Programoing has been done in assembler
language (PAL-D, Programinhle Assembler Language for DECtape) to take advantage of the shortened processing timo, to work within the 8K word memory, and to enable
the use of a single DECtape auxiliary storage unit. Processing of data was
accom-pushed at a rate-increase factor of 25 over the recorded rate (of 0.3 inches!
second) without requiring starting and stopping of the analogue playback unit.
The analogue signal comes into the A/D unit as three basic signals; the
wave-induced signal, the first-mode signal, and the combined signal. Through the use
of the analogue/digital multiplexer, each signal is digitized individually al-though the data processing is done simultaneously and continuously within the processor without the need to stop and start the playback of the analogue signal. The digitizing actually operates in terms of voltages and all processing within
the computer is on the basis of voltages. This saves core storage since twice
as many words would be necessary if stress units were stored. The specific
program flow chart is shown in Figure C-l. All references to speeds and
con-version times are in terms of real time i.e., (for a 30-minute interval). The
speed-up factor of 25 is the maximum speed at which the data can be digitized
and processed due to program and computer limitations. However, slower speeds
can be used by changing one process instruction and will be discussed further on. PROGRAN DESCRIPTION
The first 128 locations of the program contain parameters and the interrupt
service routines. The interrupt system allows for overlap (multi-processing) and
is the means by which the program is controlled.
The program interrupt can be explained as follows. When a large amount of
computing is required, the program should activate an Input/Output (I/O) device (magnetic tape, clock, etc.) and then continue the main program, rather than wait
for the slower I/O device to become ready to transfer data. The program interrupt
facility, when enabled by the program, relieves the main program of the need for
repeated flag checks by allowing the ready status of the I/O device flags to cause

Data Handling
Assemble Routine
Routi ne
-27-control transfers to a subroutine that determines which device requested the interrupt and indicates an appropriate service routine.
When an interrupt occurs, the computer automatically branches
to location
0000 and stores the last address location. Also the link, accumulator, and
program counter registers (all parts of the Central Processor Unit registers)
are stored off for later reinitlalization.
Also, the interrupt capability is
turned off. Next, the interrupt bus is checked
to see what device caused the
interrupt. An interrupt can be caused by the Magnetic Tape, Real-Time Clock
or DECtape.
An interrupt caused by any other device will not be serviced since it should not have taken place.
After the interrupt is serviced, the program branches to the dismiss
routine
(DIS). This routine re-enables the
Interrupt, restores the link, accumulator
and program counter registers and returns to the last address location prior to
the interrupt. This allows for sampling
at a fixed rate (by use of the Real-Time
Clock) and the writing of the data onto magnetic tape while handling the
arith-metic calculations needed to perform the total task.
Location 2008 to 377e contain the DECtape handler and is the standard routine
as supplied by Digital Equipment
Corporation for reading from and writing onto the DECtape unit.
The program starts at location
04008 (BEGIN), the interrupt enable is turned
off and the counters and data storage buffers are cleared and initialized.
The program types "DECTAPE ON 4? TOTAL NO. 0F VOYAGES-" then waits for the
user to respond.
If the program system tape has not already been removed, it must
be removed, and the proper logbook DECtape mounted before setting the selector
switch to unit 4. The total number of voyages to be run (in decimal: ex. 01)
is entered by the user.
After the response, the program halts. The operator then
pushes CONTINtrE on the computer console.
The program then searches the DECtape for the Initial starting block number, positiom the magnetic tape for writing, and writes the magnetic-tape label and then halts.
The header information which contains the number of intervals, number of
voyages, is
set up in a table which controls the running of the program. By
use of the table, the program is told how many intervals there are in a voyage,
which intervals are long intervals,
which
intervals are to be deleted (notdigitized), how many passes of analog tape will be run, etc. This allows the
program to run virtually unmanned,
except for data checking, reel mounting, etc.
By inputting in Halts into the table (for certain intervals) the
operator may
stop the tape at pre-planned locations. This option is especially valuable if
the operator feels problems may arise at those locations due to analogue tape
difficulties, etc.
A header to be used with
part of the Interval Summary data is typed on the
teletype. After this header is typed the
program halts. The computer and peripheral
equipment (I/O devices) are now ready to handle the data conversion phase.
After starting the FM analogue tape playback, the operator then pushes "CONTINUE"
on the computer console and the program then branches to the Calibration (CALIB) routine.
