GEOPHYSICAL LIBRARY SUBROUTINES
I.
Introduction
This report describes the various subroutines and functions in general
use by either the Geophysics Group or the present Geophysics Data Reduction
and Plotting Package (Gemperle, et al., 1976) that are not available on the
OS-3 Fortran Library (OS-3 is the operating system on the Control Data
Corporation 3300 computer at Oregon State University).
These subroutines
are available to users of the CDC-3300 on the saved file *GLIB
These subroutines may be classified into five general categories.
1.
Plotting - general purpose plotter driver subroutines and mercator map
projection subroutines.
2.
Date and Time - general purpose date and time conversion from the conventional system of year, month, day and hour, minute, second
(or tenths of minutes) to integer tenths of minutes since
the beginning of the year and the inverses of the above.
These subroutines are generally used in computations involving time differences, time output and plotting.
Various
formats are available.
3.
Arithmetic Functions - standard Fortran Library functions not available
on the OS-3 Fortran Library.
4.
Control Functions - file and operating system control functions peculiar
to the OS-3 operating system.
.5.
Misc Subroutines - subroutines used by more than one geophysics program.
These subroutines perform specific geophysically oriented
functions.
2
II.
Characteristics Common throughout the Library
This library was written to run on a CDC 3300 computer operating under
the Oregon State Open Shop Operating System (OS-3).
As such, several of the
subroutines are only applicable to this system, particularly those within
the Control Function Group.
Because OS-3 is a time sharing system, these subroutines are usually
called by programs which are normally run in an interactive mode on a teletype terminal in our offices.
These subroutines appear on the library because they are of general
enough purpose under OS-3 to be used by more than one program.
Most are
written in CDC assembly language (COMPASS), though some were written in OS-3
Fortran IV when it was applicable to the subroutine.
There are a few conventions made in the documentation of this library.
The "Type" of the parameters may be integer (I) or floating point (F.P.) for
the passing of values or single (A4) or double (A8) word variables used to
pass Binary Coded Decimal (BCD) information.
All function names appear in
the parameter table as the output parameter for the function.
Users of these subroutines and functions should also refer to the CDC
and OSU publications listed in the references relating to the OS-3 operating system, and FORTRAN and COI1PASS languages on the OSU CDC-3300 computer.

Description of Individual Subroutines
III.
A.
Plotting Subroutines
The first four subroutines are the plotter drivers and are used to
convert the pen movements in inches specified by the calling program
calls into actual pen movement codes used by the plotter and for initialization and bookkeeping.
There are no limit checks made on any of the plotter
driver subroutine parameters in order to speed up execution, therefore, care
should be used in the calling programs.
The last two subroutines are used
to generate mercator maps on a 30-inch incremental plotter.
Source listings for the first four subroutines are not included in the
Appendix because of their length.
1.
PLOTINT (X, Y, LUN)
PLOTINT is used to initialize the plotter subroutines and define
the location of the origin of the axis.
The parameters X and Y are with
respect to wherever the pen is left by the operator and are assumed to be
within six inches of the left edge of the plotter paper.
The X coordinate
is across the paper and the Y coordinate is in the long dimension of the
paper.
The normal call is:
CALL PLOTINT (-6., 6., 10).
This will cause
the origin to be against the left edge of the plotter paper and at least
six inches away from the last plot.
This is normally followed by a CALL
PLOT (1.0, 0., -3) to redefine the origin one inch from the left edge of
the plotter paper.
The logical unit, e.g. LUN 10, should have already
been defined as a plotter with an OS-3 Control Mode "EQUIP'' statement or
Fortran call to the EQUIP subroutine (see Skinner, 1970).
4
Parameter.
Description
Type
X
F.P.
The location of the X-coordinate of the axis
origin in inches relative to where the pen
was left by the operator.
Y
F.P.
The location of the Y-coordinate of the axis
origin in inches relative to where the pen
was left by the operator.
LUN
Number of the Logical Unit to which the pen
movement codes generated by the plotter driver
are sent
I
2.
PLOT (X, Y, IPEN)
PLOT is used to move the pen to a new X, Y in inches with the pen
either up or down.
If the parameter 'IPEN' is negative, then a new origin is
defined with respect to the last one defined by either PLOTINT or PLOT.
Redefinition of the origin also causes any accumulated pen movements to be
buffered to the plotter file.
This means that the last call in a plotting
program should be a call to PLOT with IPEN negative to insure that the last
record is sent to the plotter.
Parameter-

IPEN = 3 pen up prior to moving
IPEN = -3 last call to the plotter subroutines
for this plot. This defines a new origin
for subsequent plotting.
This is the basic pen movement subroutine.
The aigorithim for generating
pen movement codes was taken from CACM Algorithim 162 (Stockton, 1963).
5
3.
PLOTSYMB (X, Y, H, ARRAY, THETA, N)
PLOTSYMB is used to move the pen to the location of a centered
symbol and draw that symbol or to move the pen to the lower left corner of
a label and to write that label.
Figure 1 gives the available centered
symbols and the integer associated with each.

ROTATEXY
4.
ROTATEXY is used to rotate the axis of the plot 90 degrees counterclockwise resulting in the X-axis becoming parallel to the long dimension
of the plotter paper.
A call to this subroutine is irreversible and can
be made only once during the running of a program.
After a call to ROTATEXY
a call to PLOTINT with the parameters (0., -30., LUN) should be made to
reset the coordinate axis to the right edge of the plotter paper.
If used,
this subroutine should be the first plotter subroutine called or should only
be made when the pen is at an origin.
There are no parameters for this
sub-
routine.
MERCMAP
5.
MERCMAP is a general purpose subroutine used to generate an
annotated Mercator grid on the plotter.
It interactively asks the user
for information concerning the latitude and longitude limits, scale in
inches per degree of longitude and grid spacing in minutes as well as the
data file name and plot label (Example 1, Page 7).
printed by the subroutine MERCMAP.
Underlined characters are
MERCMAP will attempt to fit the grid
on the plotter paper with the longitude lines parallel to the length of the
paper.
If the grid will not fit, the program will rotate the grid 90 degrees
and try again.
If the minimum dimension exceeds 26 inches, the program will
ask for the map parameters again, enabling the user to split the map grid into
sections or change the scale.
MERCMAP calls the function MERIDPTS.
Subroutine MERCMAP contains the following declarative statements
for the return of input values back to the calling program:

to the EQUIP and UNEQUIP subroutines.
There are no
parameters for this
subroutine.
5.
MI
MI stores the address of the last Fortran call to MI in location
138 enabling a user to resume his program at the point of the last call to
MI by entering OS-3 Control Mode and typing "MI".
It is often used by call-
ing programs to recover from normally fatal errors in the typing of data file
names.
There are no parameters to this subroutine.

SBJP
SBJP returns the user to OS-3 control mode, effectively terminating the execution of the job.
It is equivalent to "CALL EXIT" except that
the "END OF FORTRAN EXECUTION" message is not sent to the standard output
device.
There are no parameters and the user is left in OS-3 Control Mode.
This subroutine is often used to abort the users job on a fatal error.
E.
Misc Subroutines
These subroutines preform a specific function for geophysics programs.
The first converts the revolutions of the R/V YAQUINA's engines to speed in
knots and the second accesses the Mathews table

GETMATAB (MZ, ITAB(2), IEND)
GETMATAB reads the Mathews zone table (Bialec, 1966) for the area
"MZ" from the Random Access File (RAF)
"*MATAB", and puts it in the integer
16
array "ITAB".
If the area "MZ" is not on the RAF, "*MATAB", then an error
message is written and the user is aborted.
Presently Mathews zones 23-25
and 41-45 are included on the saved public random access file "*MATAB".
The table *MATAB contains corrections to the velocity of sound assuming an
initial velocity of 1500 meters per second (See appendix B).
