B.2 Differences in Extensions and Other Features
HP COBOL on Alpha and I64 contains the following language
extensions and other features that are not in HP COBOL on VAX:
- A choice of alignment (with the /ALIGNMENT qualifier or
-align
flag) on the compile command line or as a source directive for
individual records; you can select Alpha data alignment for
performance or VAX data alignment for compatibility.
- A qualifier or flag (/ARCHITECTURE or
-arch
) that enhances performance through targeted code generation.
- A qualifier or flag (/ARITHMETIC or
-arithmetic
) that selects native or standard arithmetic.
-
A qualifier or flag (/CONVERT=LEADING_BLANKS or
-convert leading_blanks
) that changes all blanks to zeros in numeric display items in
arithmetic expressions or statements.
- A qualifier or flag (/DISPLAY_FORMATTED or
-display_formatted
) that causes the proper display of numeric values without the use of
WITH CONVERSION on the DISPLAY statement.
- A qualifier (/FLOAT) on OpenVMS Alpha that selects IEEE or
VAX floating-point data types for single- and
double-precision data items.
On Tru64 UNIX, only IEEE floating
point is supported.
On OpenVMS I64, only IEEE floating point is
supported.
- A qualifier or flag (/INCLUDE or
-include
) to control where the compiler searches for files for simple COPY
statements.
- A qualifier or flag (/MATH_INTERMEDIATE or
-math_intermediate
) to specify the intermediate data type for extended arithmetic
precision and/or compatibility.
- A qualifier or flag (/OPTIMIZE=TUNE or
-tune
) that improves optimization through instruction scheduling, and a
choice of levels of optimization (with /OPTIMIZE=LEVEL or
-On
.)
- A qualifier or flag (/RESERVED_WORDS or
-rsv
) to recognize or not to recognize additional COBOL reserved
words defined by the X/Open Portability Guide, words that are
foreign extensions, or selected words that are reserved as defined by
the draft ANSI Standard for COBOL.
- A qualifier (/TIE) on OpenVMS I64 to generate code that allows
native OpenVMS I64 images to call translated Alpha images and
translated Alpha images to call native OpenVMS I64 images.
- COMP-5 and COMP-X as synonyms for COMP.
- READ PRIOR and START LESS.
- X/Open ASSIGN TO, LINE SEQUENTIAL, RETURN-CODE, SCREEN SECTION,
FILE-SHARING, and RECORD-LOCKING.
HP COBOL on Alpha and I64 does not contain the following VAX
features:
- The DECset/LSE Program Design Facility, the /DESIGN qualifier,
design comments, or pseudocode placeholders.
HP COBOL on Alpha and I64 includes the following:
- Support for the relevant subset of the features in the HP COBOL on
VAX /STANDARD=V3 qualifier. See Section B.3.3.
- Support for file status values that are compatible with
HP COBOL for OpenVMS VAX Version 5.1 or higher. These differ from those of
Version 5.0 and previous versions.
B.3 Command-Line Qualifiers (Options or Flags)
Sections B.3.1, B.3.2, and B.3.3 compare the
HP COBOL command-line qualifiers and flags on the four operating
systems. For more information about HP COBOL command-line
qualifiers on the OpenVMS Alpha, I64, or VAX operating systems, invoke
the online help facility: Type
HELP COBOL
at the OpenVMS system prompt. For more information on the flags,
refer to the man page: Type
man cobol
at the Tru64 UNIX system prompt.
B.3.1 Qualifiers and Flags Shared by HP COBOL on Alpha, I64, and VAX
Table B-2 lists the OpenVMS command-line qualifiers shared
by HP COBOL on the Alpha, I64, and VAX platforms and the
equivalent flags on Tru64 UNIX.

1The flags are generally equivalent in features to the
qualifiers, except that flags do not have a negative form.
2There are some differences in behavior and features between
HP COBOL on Alpha, I64, and VAX. See the specific documentation
for details.
/NATIONALITY={JAPAN|US}, -nationality japan
When /NATIONALITY=JAPAN or
-nationality japan
is specified, the yen sign (¥) is the default currency sign and
symbol, and Japanese Language Support features are enabled. Also, in
this case /NODIAGNOSTICS and /NOANALYSIS_DATA are specified implicitly.
Oracle CDD/Repository is not supported when /NATIONALITY=JAPAN is used.
When /NATIONALITY=US or
-nationality us
is specified on the compile command line, the dollar sign ($) is the
default currency sign and symbol, and Japanese Language Support
features are disabled.
/STANDARD=MIA, -std mia
If /STANDARD=MIA or
-std mia
are present on the compile command line, the compiler will issue
informational diagnostics for those language elements that do not
conform to the MIA specifications:
- Hewlett-Packard syntax extension from Base Standards (ANSI-85,
JIS-88)
- Two of four optional modules
- All obsolete language elements of required modules in Base
Standards
- Language elements omitted from required modules in Base Standards
because of the different implementation of the vendors
- HP-specific Japanese features out of MIA Extension Elements
related to Japanese
To receive the diagnostics, the
-warn all
flag, /WARNINGS=ALL qualifier,
-warn information
flag, or /WARNING=INFORMATION qualifier is required.
The default is NOMIA.
