Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bodies). The work of preparing International
Standards is normally carried out through ISO technical committees. Esch member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take patt in the work. ISO
collaborates closely with the International Electrotechnical Commission (IEC) on all
matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 8651-1 was prepared by Technical Committee ISO/TC 97,
Information processing Systems.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless otherwise stated.

FORTRAN
0 Introduction
The Graphical Kerne1 System (GKS), the functional description of which is given in ISO 7942, is
specified in a language independent manner and needs to be embedded in language dependent
layers (language bindings) for use with particular programming languages. The purpose of this
part of ISO 8651 is to define a Standard binding for the FORTRAN Computer programming
language.

ISO 7942 (GKS) p fi
into a programming language, GKS is embedded in a language dependent layer obeying the par-
ticular conventions of that language. This part of ISO 8651 specifies such a language dependent
layer for the FORTRAN language.

3 The FORTRAN language binding of GKS
3.1 Specification
The GKS language binding interface for ISO FORTRAN 77 (ISO 1539) shall be described as in
clauses 3, 4, 5, 6, 7, 8, and 9.
3.2 Mapping of GKS function names to FORTRAN subroutine names
The function names of GKS are all mapped to FORTRAN subroutine names which Start with the
letter G. The mapping is generally done in a one-to-one correspondence to ISO 7942. However,
some inquiry functions are Split into more than one subroutine in this binding, due to the number
of Parameters required. The remaining letters after the first one are obtained by deriving a unique
ACTIVATE becomes AC, WORKSTATION
acronym from the words of the function name; e.g.,
becomes WK. Hence, the FORTRAN subroutine name of GKS function ACTIVATE WORKS-
TATION is GACWK. For a list of all abbreviations, see clause 4. Names used internally which
may be known outside GKS, e.g., during linking, Start with some easily recogniced and docu-
mented form such as GK (subroutine, function, and common block names). Therefore, no exter-
na1 names starting with this construct should be Chosen when using GKS, in Order to avoid name
conflicts. Globally used GKS names may be renamed if necessary.
3.3 Parameters
In general, the Order of GKS function Parameters is preserved. For some subroutines, however,
there are additional Parameters which have been inserted in the normal Parameter sequence (e.g.,
array length for arrays which are output Parameters).
Values of input Parameters are unaltered by any GKS function, by PACK DATA RECORD, or
by UNPACK DATA RECORD.
In Order that the application program may inquire any element of a list (member of a Set), such
as the set of Segment names, in this binding the inquiry functions return only a Single element of
a list (member of a Set). In addition, the total number of elements of the list (members of the
set) is always returned. The elements (members) are numbered starting from 1; each invocation
of the inquiry function requires the desired element (member) number as an input Parameter and
returns the corresponding element (member). When the list (Set) is empty, a eero is returned as
the number of elements (members) and the Parameter representing the Single element in the list is
undefined.
3.4 The FORTRAN subset
The binding for FORTRAN 77 Subset is different from that for full FORTRAN 77 in Order to
accommodate the FORTRAN 77 Subset restrictions.
Those GKS subroutines in the full FORTRAN 77 binding that have arguments of type CHAR-
ACTER*( *) have alternative subroutine definitions that include fixed length Character strings,
CHARACTER*80, for the Subset.
In some cases, an additional INTEGER Parameter (the number of characters) appears in the
Parameter list and the Subset version is distinguished by the addition of a final S, so that the two
Versions tan coexist in the same implementation. In other cases the INTEGER Parameter is
4

---------------------- Page: 12 ----------------------

SIST EN 28651-1:1997
ISO 8651-1: 1988 (E)
already present and the FORTRAN 77 Subset version has the same name as the full FORTRAN
77 veraion.
A full FORTRAN 77 implementation shall include both subroutines in the case when the names
are distinct and only the full FORTRAN 77 Version when the names are the Same.
The enumeration values in this binding may be redefined for the Subset by replacing the
PARAMETER Statements with corresponding DATA Statements.
3.5 Error handling
There are two error routines in every GKS System, named GERLOG and GERHND. The User
may replace the latter with his own subroutine using the same name, GERHND, and calling
Furthermore, this user-defined error routine may cal1 the system-defined error logging
sequence.

4 Generafing FORTRAN subroutine names
For the binding of the GKS functions which inquire lists (Sets), the word element (member) is
added to the GKS function name before the subroutine name is generated from the resulting
terms.
The derivation of the abbreviation for the subroutine names is performed in several Steps. First,
Plurals are reduced to their Singular form, and grammatical derivations are unified. Next, some
compound terms are reduced. Finally, each remaining word is replaced by the null string or by
an abbreviation.

6 Data types
In ISO 7942, Parameters of several types are used. The following Shows the correspondence
between the types used in ISO 7942 and their realisation in a FORTRAN implementation.
GKS Data Type FORTRAN Data Types
1 integer INTEGER
R real REAL
S string
In a full FORTRAN 77 subroutine:
i)
a) INTEGER containing the number of characters returned (for out-
put string argument only)
b) CHARACTER*(*) containing the string. In addition, if a charac-
ter string which is an input Parameter may reasonably contain no
characters, then an INTEGER (20) is used to give the number of
characters to be passed to the subroutine.
In a FORTRAN 77 Subset subroutine:
2)
a) INTEGER containing the number of characters passed to the sub-
routine (for input string only, i.e. only one INTEGER needed for
output).
containing the number of characters returned (for out-
b) INTEGER
put string argument only).
c) CHARACTER*80 containing the string.
P Point REAL, REAL containing the X- and Y-values
N name INTEGER
Workstation Identifier, Segment Name, Pick Identifier: An implemen-
1)
tation may restritt the range but must at least provide all non-
negative integers which are available at that implementation.
NOTE - the default value for pick identifler is Zero.
Workstation Type, Connection Identifier, Error File: The set of valid
2)
values is implementation dependent. The Connection Identifier and
Error File may be logical unit numbers.
GDP Identifier, Escape Identifier: The set of legal values is described
3)
in ISO 7942.
Identification of GKS procedure: The range is shown under
4)
‘Enumeration Types’.
E enumeration INTEGER
NOTE - All values are mapped to the range Zero to N-l, where N is the number of
enumeration alternatives. Except for null values, the Order of the enumeration alter-
natives is the same as in ISO 7942: null values always appear in the flrst Position. If
the integer value given by the application program is not in the range 0 to N-l,
there is a language binding error condition (error 2000).
const x simple-type where simple-type is 1 or R (vector of values, for example 2xR)
1) In non-inquiry functions, separate simple-type Parameters are used.
NOTE - in GKS, const 54
In inquiry functions, if const “3, separate simple-type Parameters arc
2)
used; if const 24, a simpletype array of dimension const is used.

---------------------- Page: 16 ----------------------

SIST EN 28651-1:1997
ISO 8651-1: 1988 (E)
const x P (only occurs in non-inquiry functions)
Separate REAL Parameters, with the X- and Y- coordinates of one Point
being followed by the X- and Y- coordinates of the next.
const x E (only occurrence in GKS is const = 13)
An array of INTEGER e 1 ements of dimension const is used, each element
being an enumeration alternative.
const 1 x const 2 x R (matrix of values, for example 2x3xR)
REAL array (const 1, const 2)
list of n values of one simple-type (for example nx1)
1) For input Parameter:
a) INTEGER (input Parameter) containing length n of the list (unless
the length is already present as a separate GKS Parameter, in which
case it is not duplicated)
b) array of dimension n, whose elements are of the appropriate
simple-type.
When the length could legally be eero within GKS, the binding indi-
cates the array dimension by *. The implementation Checks that
the given length is 20.
2) For output Parameter in non-inquiry functions:
a) INTEGER (input Parameter) containing the dimension of the array
b) INTEGER (output Parameter) containing the number of elements of
the array actually used.
c) an array whose elements are of the appropriate simple-type. The
input dimension being too small is a language binding error condi-
tion (error 2001).
In both cases (input or output), where the simple-type is a Point,
there is a REAL array for the X-coordinates and another for the Y-
coordinates.
3) For inquiry functions, a Single cal1 returns a Single element of the list.
For a complete list of length n,
a) INTEGER (input Parameter) containing the sequence number of
required list element (in the range O.n).
b) INTEGER (output Parameter) containing the number of items in
the list n.
a Parameter of the appropriate simple-type containing the requested
4
element.
If the sequence number given is 0, the requested element returned is
undefined, but an error is not indicated thereby; the number of
items in the list n is returned. If the sequence number given is <0
or >n, then error 2002 is indicated, the number of items in the list
is returned, but the requested element is undefined; the exception to
this is when the list siee is 0, and in that case an error is not indi-
cated thereby.
4) A complete inquired list is returned from a Single cal1 when the max-
imum siae of the list is a small constant m:
a) INTEGER (output Parameter) containing the number of elements of
the array actually used.

---------------------- Page: 17 ----------------------

is used to dimension the array. Where the data record is an output
an additional argument ‘number of array elements of data

data record contains values which are compulsory in GKS.

tion dependent, but GPREC must perform the inverse function to GUREC
and vice versa.
The representation of CELL ARRAY, PIXEL ARRAY, and PATTERN allows the user of the
routines requiring a cell array Parameter to pass any Portion of the array as an argument. Two
examples should make this clear.
The User tan pass an entire two-dimensional array. In this case the number of columns of the cell
array is the Same as the first dimension of the FORTRAN array:

To use an arbitrary Portion of an array the user Passes the upper left corner of the Portion as the
starting address and the dimensions of the entire array for the proper treatment of addresses. The
area inside the small box is the cell array being passed:
INTEGER STARTX, STARTY, DX, DY, DIMX, DIMY, CELLS (DIMX,DIMY)

6 Enumeration types
All the enumeration types of GKS are mapped to FORTRAN INTEGERs. The correspondence
between GKS scalars and FORTRAN INTEGERs is shown below in a list of symbolic FOR-
TRAN constants which may be included in any application program. The following section con-
tains a method of mapping GKS enumeration types to FORTRAN variable names. In a FOR-
TRAN 77 Subset implementation, this mapping could be accomplished by the DATA Statement.
Also, a numbering of all GKS functions is given for use in the error handling procedures.
