PRODUCT NAME: HP Fortran for OpenVMS

SPD 56.18.18

DESCRIPTION

This is the Software Product Description (SPD) for

HP Fortran (formerly Compaq Fortran) Version 8.0 for

OpenVMS™ Alpha Systems, and HP Fortran Version

8.1 for OpenVMS Integrity Servers (I64). HP Fortran on

OpenVMS Alpha contains the HP Fortran 95/90 Version

8.0 software and the HP Fortran 77 Version 8.0 software

as well as the HP Extended Math Library (CXML). In

the following description, HP Fortran refers to HP For-

tran 95/90 unless a speciﬁc reference to the 95/90 or

77 product is needed to distinguish between the two

software products.

HP Fortran is an implementation of the Fortran program-

ming language that supports the FORTRAN 66, FOR-

TRAN 77, Fortran 90, and Fortran 95 standards. HP

Fortran 95/90 and HP Fortran 77 fully support the fol-

lowing standards:

• ANSI X3.9-1966 (FORTRAN 66)

• ANSI X3.9-1978 (FORTRAN 77)

• ISO 1539-1980(E) (FORTRAN 77)

• MIL-STD-1753

• FIPS-69-1 (HP Fortran meets the requirements of

this standard by conforming to the ANSI Standard

and by including a ﬂagger. The ﬂagger optionally

produces diagnostic messages for compile-time el-

ements that do not conform to the Full-Level ANSI

Fortran Standard.)

HP Fortran 95/90 supports all of the standards that HP

Fortran 77 supports plus the following new standards:

• ANSI X3.198-1992 (Fortran 90)

• ISO/IEC 1539-1:1997(E) (Fortran 95)

HP FORTRAN

HP Fortran supports extensions to the ISO and ANSI

standards, including a number of extensions deﬁned by

HP Fortran for the various HP Fortran platforms (operat-

ing system/architecture pairs). In addition to HP Open-

VMS Alpha and I64 systems, HP Fortran platforms in-

clude:

• HP Fortran and HP Fortran 77 on HP Tru64™ UNIX®

Alpha systems

• HP Fortran 77 for OpenVMS VAX™ systems

Major additions to the FORTRAN 77 standard intro-

duced by the Fortran 90 standard include:

• Array operations

• Improved facilities for numeric computation

• Parameterized intrinsic data types

• User-deﬁned data types

• Facilities for modular data and procedure deﬁnitions

• Pointers

• The concept of language evolution

• Support for DATE_AND_TIME intrinsic for obtaining

dates using a four-digit year format

HP Fortran contains full support for the Fortran 95 stan-

dard, including the following features:

• FORALL statement and construct

• Automatic deallocation of ALLOCATABLE arrays

• DIM argument to MAXLOC and MINLOC

• PURE user-deﬁned subprograms
