QA-6KZAA-H8The Freeware CD-ROM set contains a large assortment of freeware, and is a good starting point if looking for utilities. Many of the packages listed below are also on the Freeware CD. Some of the most oft-requested OpenVMS tools on the Freeware CD include ZIP and UNZIP, GZIP, MMK (make), PINE, PERL, TAR, UUENCODE and UUDECODE. Many other tools are available on the Freeware.
The UUENCODE and UUDECODE tools and various other tools are also available as part of TCP/IP Services package. (Use the DCL command procedure SYS$STARTUP:TCPIP$DEFINE_COMMANDS.COM available on V5.0 and later to set up the necessary DCL foreign command symbols used for these and for various other tools provided by TCP/IP Services.)
Compaq also has a separate area containing various OpenVMS software tools located at:

This area is not consistently maintained, and these tools may (or may not
be) the most current versions of the tool. Please check for more recent
versions before downloading and using any particular tool.

If you get the packages via WWW or FTP, they're in ZIP format which requires the UNZIP (note: this is not Gnu gunzip!) tool to unpack. You can get ZIP and UNZIP from the following areas:
ftp://ftp.wku.edu/vms/unzip.exe for VAX
ftp://ftp.wku.edu/vms/unzip.alpha_exe for Alpha

or you can request the FILESERV_TOOLS package from the e-mail server.
[Beware: The [000TOOLS...] pre-built versions of ZIP on the OpenVMS Freeware V4 CD-ROM will erroneously return BILF errors on OpenVMS V7.2 and later. Use of the source on the Freeware V4 to rebuild the ZIP image(s), or acquiring a pre-built ZIP image from one of the above areas can avoid this. The pre-built version of ZIP on the Freeware V4 kit is older than the included ZIP sources, and it contains a latent bug.]

I have written and installed on INFO.CS.PUB.RO an "Archie" clone for VMS
software. Telnet to that machine, and login as VMSARCI.
It contains now listings for over 30 ftp servers with more than 14GB of VMS software.
The most useful commands are LIST, which generates a list of scanned ftp
servers, and FIND <string>, whichs looks for a file containing "string"
in the name; the search modes are only "substring" [default] and "exact",
and regex search is not supported (so FIND EMACS will work, but FIND *EMACS*
or FIND *EMACS*.* will not). The search is case-insensitive.
Those of you that know other ftp servers with VMS software that I haven't
found, please let me know. (The program that build the databases can
recursively scan whole servers- as FTP.WKU.EDU, or just some directories-
as NIC.SWITCH.CH/pub/vms)
Sorry, this service is VERY SLOW [by Western standards], because it runs
on a quite-busy oldie-but-goodie VAXStation 3400 with 20Mb and a RF71, and
the Internet link is only 256 Kpbs (sometimes unavailable).

Java is not available on OpenVMS VAX. As for why: the Java language definition requires a floating point format (IEEE) that is not native to VAX, and this would require the emulation of all floating point operations within Java applications. Further, the C source code used to implement for Java itself is heavily dependent on passing IEEE floating point values around among the many internal subroutines, and adding support for VAX would entail changes to the Compaq C compiler for OpenVMS VAX - and specifically to the VAX VCG code generator that is used by Compaq C on OpenVMS VAX systems - in order to add support for passing IEEE-format floating point doubles around. Alternatively, extensive changes to the Java source code to remove the assumption that the double is an IEEE floating point value.
There are currently no plans to make a version of Java available for OpenVMS VAX. (A prototype version of Java was created for OpenVMS VAX, and performance was found to be inadequate at best.)
If Java2 or other environment lifts the requirements for IEEE floating point as part of the language definition, this decision may be revisited.
For additional information on Java for Alpha systems, please see the OpenVMS documentation (V7.2 and later), and the following site:
http://www.compaq.com/java/alpha/index.html
Both compilers can be installed at the same time on the same OpenVMS VAX system, allowing a migration from VAX C to DEC C, and allowing the same DEC C code to be used on OpenVMS VAX and OpenVMS Alpha. In 1999, the C compiler version is Compaq C V6.0.
The system manager can choose the system default C compiler when Compaq C is installed on a system with VAX C, and a C programmer can explicitly select the required compiler for a any particular compilation.
A current "C" license PAK allows access to both VAX C and Compaq C on the same OpenVMS VAX system.
Various Compaq C versions can be installed on OpenVMS VAX V5.5-2 and later. OpenVMS VAX releases such as V5.5-2 and V6.0 will require the installation of a Compaq C RTL kit, a kit that is included with the Compaq C compiler. OpenVMS VAX versions V6.1 and later do not require a seperate RTL kit, but Compaq C RTL ECO kits are available to resolve problems found with the C RTL on various OpenVMS releases.
With Compaq C, for automatic resolution of the standard C library routines by the LINKER utility, use the /PREFIX qualifier, such as PREFIX=ALL_ENTRIES. If a particular application program replaces an existing C library routine, use /PREFIX=(ALL_ENTRIES,EXCEPT=(...)). VAX C required explicit specification of an RTL shareable image or C object library during the link.)
When the /PREFIX is requested, the compiler generates a "decc$" prefix on the specified symbols. This prefix allows the LINKER to resolve the external symbols against the symbols present in the DECC$SHR library. The DECC$SHR library is included in the IMAGELIB.OLB shareable image library, and IMAGELIB is searched by default when any program (written in any language) is LINKed. Because the standard C library routine names are very likely to match application routines written in other languages, a prefix "decc$" is added to the C symbol names to assure their uniqueness; to prevent symbol naming conflicts. C programs, however, can sometimes have private libraries for various purposes, and the external routines share the same names as the library routines. This is not recommended, but there are applications around that use this technique.) Thus the need to explicity specify whether or not the "decc$" prefix should be prepended to the external symbol names by the compiler.
The qualifiers, and most (all?) with associated pragmas, that may be of interest when migrating VAX C code to Compaq C include:
Permit structure members to be naturally aligned whenever possible, and avoid using /NOMEMBER_ALIGNMENT. If you need to disable member alignment, use the equivilent #pragma to designate the specific structures. The alignment of structure members normally only comes into play with specific unaligned data structures - such as the sys$creprc quota itemlist - and with data structures that are using data that was organized by a system using byte or other non-member alignment.
Versions of Compaq C such as V6.0 include the capability to extract the contents of the standard header libraries into directories such as SYS$SYSROOT:[DECC$LIB...], and provide various logical names that can be defined to control library searches. With Compaq C versions such as V6.0, the default operations of the compiler match the expectations of most OpenVMS programmers, without requiring any definitions of site-specific library-related logical names. (And logical names left from older DEC C versions can sometimes cause the compiler troubles locating header files.)
Compaq C V5.6 and later include a backport library, a mechanism by which Compaq C running on older OpenVMS releases can gain access to newer RTL routines added to the RTL in later OpenVMS releases - the language RTLs ship with OpenVMS itself, and not with the compilers.
Example C code is available in SYS$EXAMPLES:, in DECW$EXAMPLES (when the DECwindows examples are installed), in UCX$EXAMPLES (when Compaq TCP/IP Services is installed), on the Freeware CD-ROMs, and at web sites such as
http://www.openvms.compaq.com/wizard/
Other common C issues:
The C epoch typically uses a longword (known as time_t) to contain the number of seconds since midnight on 1-Jan-1970. At the current rate of consumption of seconds, this longword is expected to overflow (when interpreted as a signed longword) circa 03:14:07 on 19-Jan-2038 (GMT), as this time is circa 0x7FFFFFFF seconds since the C base date. (The most common solution is to ensure that time_t is an unsigned.)
If C does not correctly handle the display of the local system time, then check the UTC configuration on OpenVMS -- the most common symptom of this is a skew of one hour (or whatever the local daylight savings time change might be). This skew can be caused by incorrect handling of the "is_dst" setting in the application program, or by an incorrect OpenVMS UTC configuration on the local system. (See section TIME4.)
Other common C++ issues:
Compaq C++ (a separate compiler from Compaq C) provides both symbol
mangling and symbol decoration. Some of the details of working with
longer symbol names and the resulting symbol name mangling in mixed
language environments are listed in the shareable image cookbook,
and in the C++ documentation. Symbol name decoration permits the
overloading of functions (by adding characters to the external symbol
for the function to indicate the function return type and the argument
data types involved), and mixed-language external references can and
often do need to disable this decoration via the extern "C" declaration
mechanism:
extern "C"
{
extern int ExternSymbol(void *);
extern int OtherExternSymbol(void *);
}
Also see ALPHA16 for information on /ARCHITECTURE and /OPTIMIZE=TUNE.
If you use the POST method, then you need to read the form data from stdin. For a DCL CGI script running under the Netscape FastTrack web server, you can read the data using the following READ command:

"entry_number","display_entry","this_job")

[Peter Weaver]
To perform the "conversion", issue the following commands for each CMS library present:
$ RENAME disk:[directory]00CMS.* 01CMS.*
$ COPY NLA0: disk:[directory]00CMS.CMS
The new file 00CMS.CMS must have the same security settings as the
01CMS.CMS file, and is created solely to ensure continued compatibility
with tools that expect to find a 00CMS.CMS file (eg: various versions
of the Language-Sensitive text editor LSEDIT).

In this case, use of a file containing nolinemode commands or other techniques might be useful - you will want to ensure that the text editor you use does not attempt to use screen mode or similar, as this is not generally considered adventageous within a command procedure.
Tools such as FTP have alternatives: COPY/FTP.
DCL symbol substitution occurs in two passes, using the ampersand and the apostrophe. In most cases, only the apostrophe is necessary. In a few cases - such as the DCL PIPE command - you will may need to use the ampersand to get the substitution to work. The following example uses ampersand substitution to transfer the contents of the header into a logical name:
$ PIPE CC/VERSION | (READ SYS$PIPE hdr ; DEFINE/JOB/NOLOG hdr &hdr )A logical name (in the job logical name table; shared by all processes in the current job) was used as DCL symbols cannot be returned back out from a DCL PIPE or other spawned subprocess.
