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, governmen-
tal and non-governmental, in liaison with ISO, also take part 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
75 070 approval by the member bodies voting.
International Standard ISO 8651-3 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.
ISO 865 1 consists of the following Parts, under the general title Information processing

Introduction
0
The Graphical Kerne1 System (GKS) (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 Ada Computer programming language.

1 Scope and field of application
ISO 7942 (GISS) specifies a language independent nucleus of a graphics System. For integration into a
programming language, GKS is embedded in a language dependent layer obeying the particular conventions of that
language. This part of ISO 8651 specifies such a language dependent layer for the Ada language.

ISO 8651-3 : 1988 (E)
3 The Ada language binding of GKS
This binding does not assume that the Compiler supports any Ada language features which are implementation
dependent, but implies that the Compiler shall be able to support the declarations contained in this GKS/Ada binding.
This binding does not make any assumptions regarding the machine representation of t;he predefined Ada numeric
types.
This binding assumes that the application programmer will supply an error file name and connection identifier that
are in an acceptable formst for the Ada implementation.
This binding makes no assumptions regarding the format of a string specifying an error file name or connection
identifier for devices or metafiles.
3.1 Conformance
This binding incorporates the rules of conformance defined in the GKS Standard (ISO 7942) for GKS
implementations, with these additional requirements specifically defined for Ada implementations of GKS.
The following criteria are established for determining conformance or non-conformance of an implementation to this
binding:
a) An implementation of GKS in Ada conforms to a level of GKS if it makes visible exaclly the
declarations for that level of GKS and lower levels of GKS as stated in this binding.
b) The semantics of an implementation shall be those stakd in the GKS Standard as modified
or extended for Ada as stated in this binding document.
c) The package corresponding to the GKS level being implemented shall be an available
Ada library unit, with all names as specified by this document.
3.2 Implications sf the language
3.2.1 Functional mapping
The functions of GKS are all mapped to Ada procedures. The mapping utilizes a one-to-one correspondence between
the GKS functions and Ada procedures, except for the GKS functions Inquire Current Primitive Attribute Values and
Inquire Current Individual Attribute Values. These are bound with one Ada procedure for each of the attributes being
inquired; in addition, the attributes are bound as a Single record.
3.2.2 Implementation and host dependencies
There are a number of implementation and host dependencies associated with the Ada Compiler and runtime System
used. These will affect the portability of application programs and their use of GKS. The application programmer
should follow accepted practices for ensuring portability of Ada programs to avoid introducing Problems when
rehosting the application on another System. Implementation dependencies include runtime storage management and
processor management.
3.2.3 Error handling
The inquiry functions utilize error indicator Parameters for the error returns, and do not raise Ada
exceptions. The application program must ensure that these error indicators are checked before attempting
to access other Parameters, since some Ada implernentations do not raise an exception if an undefined value
is accessed.
The error handling requirements of GKS tan be summarized as follows:

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

SIST EN 28651-3:1997
ISO 8651-3 : 1988 (E)
1 . By default, a procedure named ERROR HANDLING will be provided
that simply reports the error by calling ERRORLOGGING. This is
called from the GKS function that detects the error.
The ERROR-HANDLING procedure may be replaced by one defined by
2 .
the User.
The procedure ERROR-HANDLING is defined as a library subprogram:
with GKS TYPES;
use GKS -TYPES;
procedur;ERROR HANDLING (ERROR INDICATOR : inERROR NUMBER;
-
GKS FÜNCTION : inSTRING~
: inSTRING
ERRÖR FILE
-
:=DEFAULT ERROR FILE);
- -
--
The procedure ERROR HANDLING is defined as a library subprogram, and is not
-- declared within packagcGKS.
This binding defines two different bodies for this subprogram; each must be supplied by the
implementation. The default body is the one required by GKS semantics. It simply calls
ERROR LOGGING and retums. The second body calls ERROR-LOGGING and then raises the exception
GKS ERKOR. The GKS function must be written so as not to handle GKS ERROR (this is a requirement
of th~implementation). Thus, by Ada rules, the exception will be propagatedback to the application
program that called the GKS function in which the error was detected.
The means by which the user replaces the default body of either the exception-raising version or another one
of bis or her choosing is dependent upon the Ada library manager. Some implernentations support multiple
Versions of a body with a Single specification or otherwise allow hierarchical libraries with the sharing of
common units. In other implernentations it may be necessary to duplicate the GKS library for each version
of ERROR HANDLING.
-
GKS errors are mapped to the Single exception GKSERROR, declared in the GKS package. The expected
style in dealing with errors using exception handling is to provide a handler for the GKS ERROR
-
exception.
3.2.4 Data mapping
The simple and compound data types of GKS are bound to a variety of Ada scalar and compound types. Constraints
on permitted values arc reflected where possible in the type definitions. The general correspondence between the
GKS data types and Ada binding data types is summarized below:
GKS integers are mapped to Ada integer types.
GKS reals are mapped to Ada floating-point types.
GKS strings are mapped to the predefined Ada type STRING, or to a type providing for
variable length strings.
GKS Points are mapped to Ada record types.
GKS names are mapped to Ada discrete types.
GKS enumeration types are mapped to Ada enumeration types.
GKS vectors are mapped to Ada record types.
5

---------------------- Page: 13 ----------------------

SIST EN 28651-3:1997
ISO 8651-3 : 1988 (E)
GKS matrices are mapped to Ada array types.
GKS lists (of elements of a particular type) are mapped to an Ada private
type declared in an instantiation of the generic GKS~LISTJJTILITIES package.
GKS arrays are mapped to either an unconstrained Ada array type, or to a record type providing
for variable length arrays.
GKS ordered pairs are mapped to Ada record types.
GKS data records are mapped to Ada private types. In some cases a set of subprograms for
operating on the data records are explicitly defined by this binding.
This is because the content and
structure of the data record is implementation-dependent. An implementation of GKS may provide
other subprograms for manipulating implementation-dependent data records.
3.2.5 Multi-tasking
The Ada language definition provides explicit support for concurrency. The Ada tasking model includes facilities for
declaring and allocating tasks, and operations allowing intertask communication and synchronization.
The GKS Standard, and hence this binding, neither requires nor prohibits an implementation from protecting against
problems which could arise from asynchronous access to the GKS data structures from concurrent tasks.
Implernentors of GKS should provide information in the user’s documentation regarding whether protection against
such Problems is implemented.
Annex D contains guidelines for implernentors who want to support multi-tasking application programs. This
annex does not form an integral part of the binding Standard, but provides additional information.
3.2.6 Packaging
The GKS Standard defines nine levels of graphic functionality, with level Oa as the lowest level and level2c as the
An implementation of GKS may implement every level individually or as a Single System. To
highest level.
support this concept this binding defines nine Ada packages which correspond to each of the GKS levels. Esch of
these packages is named
package GKS is . . . end GKS;
to provide portability of application programs for levels of GKS. However, the contents of the packages differ
depending on the level of GKS that they provide. Esch of these packages provides the subprograms defined for its
level and all subprograms defined in “lower” levels as described in 5.1 of this binding. Associated with each of these
packages is a data type package which provides the type declarations for the appropriate level as defined in 4.2 and the
GKS defined exception defined in 4.3.1. These packages are named
package GKS TYPES is . . . end GKS TYPES;
- -
The Ada program library facility should be used to provide the levels Separation. Thus, an Ada graphics application
program which uses GKS would “with” the appropriate GKS packages which provide the subprogram, types, and
exceptions for that level by compiling and linking to the corresponding Ada library which contains that level of GKS.
For example, an application which uses level Oa would “with” the packages as follows:
with GKS;
use GKS TYPES;
procedure-ÄPPLICATION is
begin
null;
end APPLICATION;

---------------------- Page: 14 ----------------------

SIST EN 28651-3:1997
ISO 8651-3 : 1988 (E)
Then the program is compiled and linked to the Ada program library that corresponds to level Oa.
Several additional Ada units are defined in this binding. These are:
o generic package GKS COORDINATE SYSTEM
- -
o generic package GKS~LISTJI’ILITIES
These generic packages support the declaration types in the GKS TYPES package described above. The
GKS COORDINATE SYSTEM is a generic package that defines an-&sortment of types for supporting each of
-
the C?& coordinate Systems. GKSLIST-UTILITIES is also a generic package which provides type declarations
and operations for list types which correspond to the GKS list types.
3.2.7 Application program environment
An application program utilizing an Ada implementation of GKS will need to be aware of the environment in which
both GKS and the application program reside.
One such interface is the Ada program library. The Ada language requires that the application program have access
to the program library in which the GKS Software resides. The ISO 8652 Ada Reference Manual does not specify
whether there is a Single library or multiple libraries, or how access to the libraries is granted, managed, etc. The
user’s documentation for the GKS implementation should specify where the GKS library exists in the System, and
how access to the library is acquired.
Input/Output interfaces are also implementation-dependent, and are required to be described in the user’s
documentation. Besides the obvious graphics device interface information, interfaces to the file System shall be
included in the documentation. Specifically, this includes the interface to the GKS error file and also the metafile
storage.
3.2.8 Registration l)
The GKS Standard reserves certain value ranges for registration as graphical items. The registered graphical items
will be bound to Ada (and other programming languages). The registered item bindings will be consistent with the
binding presented in the document.
For the purpose of this part of ISO 8651 and according to the rules for the designation and Operation of registration
1)
authorities in the ISO Directives, the ISO Council has designated the National Bureau of Standards (Institute of Computer Sciences
and Technology) A266 Technology Building, Gaithersburg, MD, 20899, USA to act as registration authority.
