PRODUCT NAME: HP Pascal For OpenVMS

SPD 25.11.55

DESCRIPTION

This document addresses HP Pascal Version 6.0 for

OpenVMS Alpha, HP Pascal Version 5.8 for OpenVMS

VAX, and HP Pascal Version 6.0 for OpenVMS Integrity

Servers (I64).

HP Pascal is an implementation of the Pascal language

that accepts programs compatible with either level of

the ISO speciﬁcation for Programming languages - Pas-

cal ([ISO 7185-1987]) as well as (ANSI/IEEE 770X3.97-

1987). HP Pascal also meets the Federal Informa-

tion Processing Standard Publication ((FIPS-109)) re-

quirements by accepting programs conforming to the

ANSI standard. HP Pascal also accepts many features

from the Extended Pascal standard ((ANSI/IEEE 770X3.

160-1989) and (ISO 10206)).

The compiler has been validated for both levels of the

ISO unextended Pascal standard and for conforming to

FIPS-109. Containing extensions to the standards, HP

Pascal generates optimized, shareable code that takes

full advantage of the VAX, Alpha and Itanium hardware

ﬂoating point and character instruction sets and the vir-

tual memory capabilities of the OpenVMS VAX, Alpha

and I64 Operating Systems. The language contains

control statements, data types, and predeclared proce-

dures and functions.

Major Pascal Language Elements:

• INTEGER, REAL, CHAR, BOOLEAN, enumerated,

and subrange data types

• ARRAY, RECORD, SET, and FILE structured data

types

K.Jensen and N. Birth ,Pascal User Manual and Report,2nd.ed., Spring-Verlag,

New York 1974.

• Schemata type denoting families of types

• STRING schema denoting variable-length character

strings up to 65,535 characters

• FOR, REPEAT, and WHILE repetitive control state-

ments

• CASE, IF-THEN, and IF-THEN-ELSE conditional

statements

• BEGIN...END compound statement

• User-deﬁned procedures and functions that can re-

turn structured types (other than ﬁle types)

• GET, PUT, READ, WRITE, READLN, and WRITELN

input and output procedures

• Concatenation operator and set of predeﬁned char-

acter string functions including INDEX, LENGTH, and

SUBSTR

• Standard set of functions, procedures, and operators

• Module initialization and ﬁnalization

• Initial state speciﬁcation

• Enhanced structured value constructors

• Implementation characteristics (MAXCHAR, MINREAL,

MAXREAL, EPSREAL)

• OTHERWISE clause and case ranges for CASE

statement and variant records

• Date and Time functions and procedures

• Short Circuit Boolean Operators (AND_THEN and

OR_ELSE)

• Non-Decimal representation of numbers

• Exponentiation operator (**)
