Foreword
ISO (the International Organization for Standardization) and IEC (the Inter-
national Electrotechnical Commission) form the specialized System for worldwide
standardization. National bodies that are members of ISO or IEC participate in the
development of International Standards through technical committees established
by the respective organization to deal with particular fields of technical activity.
ISO and IEC technical committees collaborate in fields of mutual interest. Other
international organizations, governmental and non-governmental, in liaison with
ISO and IEC, also take part in the work.
In the field of information technology, ISO and IEC have established a joint
technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the
joint technical committee are circulated to national bodies for voting. Publication
as an International Standard requires approval by at least 75 % of the national
bodies casting a vote.
Amendment 1 to International Standard ISO/IEC 95934: 1990 was prepared by
Joint Technical Committee ISO/IEC JTC 1, Information technology.

Introduction
Repke the Irmoduction of ISO/IEC 9.593-1 with th.e following text:
. .
ISO/IEC 9592- 1: 1989, provides a set of functions for the display and modification of 2D or 3D graphical
data. Part 1 is extended by Part 4 (PHIGS PLUS) to incorporate the effects of lighting, shading and other
properties that are important for the display of surfaces and multidimensional data.
ISO/IEC 9592-1 and ISO/IEC 9592-4 are specified in a language independent manner and must be embedded
in language dependent layers (language bindings) for use with particular programming languages.
The purpose of this part of ISO/IEC 9593 is to define the FORTRAN language binding for ISO/IEC 9592-1
and ISO/IEC 9592-4.

Replnce clcruse 1:
The “Programmer’s Hierarchical Interactive Graphits System” (PHIGS), ISO/IEC 9592-1: 1989, and ISO/IEC
9592-4: 1992, specify a language independent nucleus of a graphics System. For integration into a
programming language, PHIGS PLUS is embedded in a language dependent layer obeying the particular
conventions of that language. This part of ISO/IEC 9593 specifies the FORTRAN language dependent layer.

3 Principles
3.1 Specifxation
Replace suhclause 3.1, Specificntion, of ISOLEC 9593-1 with the following text:
. . .
This part of ISO/IEC 9593 defines the PHIGS and PHIGS PLUS language binding interface for FORTRAN
77, as described in ISO 1539: 1980. With some minor modifications, application programs tan be transported
between full FORTRAN77 and FORTRAN77 Subset PHIGS and PHIGS PLUS installations.
This binding incorporates the rules of conformance defined in the PHIGS (ISO!IEC 9592-1) and PHIGS
PLUS (ISO/rEC 9592-4) Standard for PHIGS and PHIGS PLUS implernentations, with those additional
requirements specifically defined for FORTRAN language implernentations defined in this part of ISO/IEC
9593. The following criteria are established for determining conformance of an implementation to this
binding:
In Order to conform, an implementation of the FORTRAN bindin, * of PHIGS shall implement those
functions specified in ISO/IEC 9592- 1. The implementation shall make visible all of the declarations in the
FORTRAN binding specified in clause 5 to 10 in this part of ISO/IEC 9593.
In Order to conform, an implementation of the FORTRAN binding of PHIGS PLUS shall implement
those functions specified in ISO/IEC 9592-1 and also those functions specified in ISO/IEC 9592-4. The
implementation shall make visible all of the declarations in the FORTRAN binding specified in clause 11 to
14 and in clause 5 to 10, as modified by clause 11 to 14, in this part of ISO/IEC 9593.
Thus, for example, the Syntax of the function names shall be precisely as specified in this part of
ISO/IEC 9593 and the Parameters shall be of the data types stated in this part of ISO/IEC 9593.
A PHIGS FORTRAN application should run without modification under a PHIGS PLUS
FORTRAN binding implementation.
3.2 Mapping of PHfGS function names to FORTRAN subroutine names
Append the following pmqyq~h to subclnuse 3.2,
.
However, two abbreviations are changed for PHIGS PLUS; MAPPING becomes M and WORKSTATION
becomes W, due to the FORTRAN subroutine naming restrictions.
3.3 Parameters
No clwnge to ISOLEC 9.593-1.
3.4 The FORTRAN subset
No ch.ange to ISO/IEC 9593-1.

All the enumeration types of PHIGS PLUS are mapped to FORTRAN INTEGERs. The correspondence
between PHIGS PLUS scalars and FORTRAN INTEGERs is shown as follows in a list of symbolic
FORTRAN constants that may be included in any application program. This clause contains a mapping of
PHIGS PLUS enumeration types to FORTRAN variable names.
“Polyline shading method”, “interior shading method”, “data mapping method”, “reflectance property type”
“reflectance model”, “curve placement”, “light Source type”, “colour mapping method”, “curve approximation
“surface approximation type” and “parametric surface charcteristic type” are defmed as INTEGER

rather than enumeration types in PHIGS PLUS. Constant definitions for the explicitly defined and required
values of these conceptually unbounded ranges arc provided as a convenience.
Also, a numbering of all PHIGS PLUS functions is given for use in the error handling procedures.
