$!
$!     Build procedure for VMS versions of Zip.
$!
$!     last revised:  2007-03-15  SMS.
$!
$!     Command arguments:
$!     - suppress help file processing: "NOHELP"
$!     - suppress message file processing: "NOMSG"
$!     - select link-only: "LINK"
$!     - select compiler environment: "VAXC", "DECC", "GNUC"
$!     - select large-file support: "LARGE"
$!     - select compiler listings: "LIST"  Note that the whole argument
$!       is added to the compiler command, so more elaborate options
$!       like "LIST/SHOW=ALL" (quoted or space-free) may be specified.
$!     - supply additional compiler options: "CCOPTS=xxx"  Allows the
$!       user to add compiler command options like /ARCHITECTURE or
$!       /[NO]OPTIMIZE.  For example, CCOPTS=/ARCH=HOST/OPTI=TUNE=HOST
$!       or CCOPTS=/DEBUG/NOOPTI.  These options must be quoted or
$!       space-free.
$!     - supply additional linker options: "LINKOPTS=xxx"  Allows the
$!       user to add linker command options like /DEBUG or /MAP.  For
$!       example: LINKOPTS=/DEBUG or LINKOPTS=/MAP/CROSS.  These options
$!       must be quoted or space-free.  Default is
$!       LINKOPTS=/NOTRACEBACK, but if the user specifies a LINKOPTS
$!       string, /NOTRACEBACK will not be included unless specified by
$!       the user.
$!     - select installation of CLI interface version of zip:
$!       "VMSCLI" or "CLI"
$!     - force installation of UNIX interface version of zip
$!       (override LOCAL_ZIP environment): "NOVMSCLI" or "NOCLI"
$!     - select BZIP2 support: "IZ_BZIP2=dev:[dir]", where "dev:[dir]"
$!       (or a suitable logical name) tells where to find "bzlib.h".
$!       The BZIP2 object library (LIBBZ2_NS.OLB) is expected to be in
$!       a "[.dest]" directory under that one ("dev:[dir.ALPHAL]", for
$!       example), or in that directory itself.
$!
$!     To specify additional options, define the global symbol
$!     LOCAL_ZIP as a comma-separated list of the C macros to be
$!     defined, and then run BUILD_ZIP.COM.  For example:
$!
$!             $ LOCAL_ZIP == "VMS_IM_EXTRA"
$!             $ @ [.VMS]BUILD_ZIP.COM
$!
$!     Valid VMS-specific options include VMS_PK_EXTRA and VMS_IM_EXTRA. 
$!     See the INSTALL file for other options.  (VMS_PK_EXTRA is the
$!     default.)
$!
$!     If editing this procedure to set LOCAL_ZIP, be sure to use only
$!     one "=", to avoid affecting other procedures.  For example:
$!             $ LOCAL_ZIP = "VMS_IM_EXTRA"
$!
$!     Note: This command procedure always generates both the "default"
$!     Zip having the UNIX style command interface and the "VMSCLI" Zip
$!     having the CLI compatible command interface.  There is no need to
$!     add "VMSCLI" to the LOCAL_ZIP symbol.  (The only effect of
$!     "VMSCLI" now is the selection of the CLI style Zip executable in
$!     the foreign command definition.)
$!
$!
$ on error then goto error
$ on control_y then goto error
$ OLD_VERIFY = f$verify( 0)
$!
$ edit := edit                  ! override customized edit commands
$ say := write sys$output
