!!
!! Define the verb VVENCODE.
!!
!! Parameters
!!
!! INPUT_FILE
!!
!! The file to be read and encoded. This parameter is required
!! (unless the /HELP qualifier is present) and must be a valid
!! VAX/VMS file specification.
!!
!! OUTPUT_FILE
!!
!! The encoded VVE file to be created by VVENCODE. This
!! parameter is optional, but if present, must be a valid
!! VAX/VMS file specification.
!!
!! Qualifiers
!!
!! /DEBUG
!!
!! generate copious debugging information
!!
!! /ENCODING_TABLE=file-spec
!!
!! specify a file containing the 64 character encoding table
!! used to encode/decode the file. The qualifier value is
!! required and must be a valid VAX/VMS file specification.
!!
!! /FORMAT=file_format
!!
!! specify the VVcode file format to be used when reading the
!! file. This qualifier is not normally required as the file
!! format will be determined automatically by the program. The
!! qualifier value is required and must be one of the values
!! defined for the CLD type 'file_format' (defined near the end
!! of this file): DEFAULT, FIXED, STREAM or VARIABLE.
!!
!! /HEADER_FILESPEC=string
!!
!! specify the file specification to be recorded in the VVE
!! file created by VVENCODE, to be subsequently used as the
!! default for the output file by VVDECODE. The qualifier value
!! is required and may be an arbitrary string. The value is not
!! checked or validated by VVENCODE.
!!
!! /HELP
!!
!! request a short summary of the command line syntax for
!! VVENCODE. NOTE: this qualifier invokes a special syntax
!! version of the verb that does not require an input file to be
!! specified.
!!
!! /LOG[=file_spec]
!!
!! specify a file to which status and logging information should
!! be written. The qualifier value is optional, but if present,
!! must be a valid VAX/VMS file specification. If absent,
!! logging information is written to SYS$OUTPUT.
!!
!! /MODE=file_mode
!!
!! specify the VVcode file mode to be used when reading the file.
!! This qualifier is not normally required as the file mode
!! will be determined automatically by the program. The
!! qualifier value is required and must be one of the values
!! defined for the CLD type 'file_mode' (defined near the end
!! of this file): BINARY or TEXT.
!!
!! /OVERWRITE
!!
!! specify that existing files can be overwritten by VVENCODE
!! without first requesting permission. On VAX/VMS, VVENCODE
!! would only request permission if the output file
!! specification included an explicit version number.
!!
!! /RECORD_LENGTH=decimal_number
!!
!! specify the maximum record length to be assumed when reading
!! a fixed or variable length record format file. This
!! qualifier is not normally required as the maximum record
!! length will be determined automatically by the program. The
!! qualifier value is required and must be an integer in the
!! supported for the different file formats (FIXED: 2 - 32767,
!! VARIABLE: 0 - 32765).
!!
!! /SPLIT_SIZE=decimal_number
!!
!! specify the maximum size in kilobytes of VVE file parts
!! created by VVENCODE. The qualifier value is required and must
!! be an integer no less than 4.
!!
!! /TIMESTAMP=time_value
!!
!! specify the timestamp to be recorded in the VVE file created
!! by VVENCODE, to be subsequently used by VVDECODE. The
!! qualifier value is optional, but if present, must be a VMS
!! absolute or combination time. If the qualifier value is
!! omitted the current date and time is used. This
!! qualifier is not normally required as the file timestamp
!! will be determined automatically by the program.
!!
!! /TRANSLATION_FILE=file_spec
!!
!! specify a file containing the rules for translating between
!! two character sets (e.g. ASCII -> EBCDIC). The qualifier
!! value is required and must be a valid VAX/VMS file
!! specification.

!! Define the verb VVDECODE.
!!
!! Parameters
!!
!! INPUT_FILE
!!
!! The encoded VVE file to be read and decoded. This parameter
!! is required (unless the /HELP qualifier is present) and must
!! be a valid VAX/VMS file specification.
!!
!! OUTPUT_FILE

!! /DEBUG

!!
!! /ENCODING_TABLE=file-spec
!!
!! specify a file containing the 64 character encoding table
!! used to encode/decode the file. The qualifier value is
!! required and must be a valid VAX/VMS file specification.
!!
!! /FORMAT=file_format
!!
!! specify the VVcode file format to be used to create the
!! output file. This qualifier is not normally required as the
!! VVE file specifies the format of the original file, but may
!! be used to override that value. The qualifier value is
!! required and must be one of the values defined for the CLD
!! type 'file_format' (defined near the end of this file):
!! DEFAULT, FIXED, STREAM or VARIABLE.
!!
!! /HELP
!!
!! request a short summary of the command line syntax for
!! VVDECODE. NOTE: this qualifier invokes a special syntax
!! version of the verb that does not require an input file to be
!! specified.
!!
!! /INDEX_FILE=file_spec
!!
!! specify a file containing the index of translation table
!! files to be used for translating between two character sets
!! (e.g. ASCII -> EBCDIC). The qualifier value is required and
!! must be a valid VAX/VMS file specification. This file is
!! used by VVDECODE if the file has been encoded using a
!! different character set and the /TRANSLATION_FILE qualifier
!! was not used to specify the translation table file.
!!
!! /LOG[=file_spec]
!!
!! specify a file to which status and logging information should
!! be written. The qualifier value is optional, but if present,
!! must be a valid VAX/VMS file specification. If absent,
!! logging information is written to SYS$OUTPUT.
!!
!! /MODE=file_mode
!!
!! specify the VVcode file mode to be used to create the
!! output file. This qualifier is not normally required as the
!! VVE file specifies the mode of the original file, but may
!! be used to override that value. The qualifier value is
!! required and must be one of the values defined for the CLD
!! type 'file_mode' (defined near the end of this file):
!! BINARY or TEXT.
!!
!! /OVERWRITE
!!
!! specify that existing files can be overwritten by VVDECODE
!! without first requesting permission.
!!
!! /PAD_CHARACTER=decimal_number
!!
!! specify the value of the character to be used to pad a fixed
!! length format output file to ensure that its length is an
!! exact multiple of the record length. The qualifier value is
!! required and must be an integer in the range 0 - 255.
!!
!! /RECORD_LENGTH=decimal_number
!!
!! specify the maximum record length to be used when creating
!! a fixed or variable length record format file. This
!! qualifier is not normally required as the VVE file specifies
!! the maximum record length of the original file. The
!! qualifier value is required and must be an integer in the
!! supported for the different file formats (FIXED: 2 - 32767,
!! VARIABLE: 0 - 32765).
!!
!! /TIMESTAMP=time_value
!!
!! specify the timestamp to be applied to the output file
!! created by VVDECODE. This qualifier is not normally required
!! as the VVE file specifies the timestamp of the original file.
!! The qualifier value is optional, but if present, must be a VMS
!! absolute or combination time. If the qualifier value is
!! omitted the current date and time is used.
!!
!! /TRANSLATION_FILE=file_spec
!!
!! specify a file containing the rules for translating between
!! two character sets (e.g. ASCII -> EBCDIC). The qualifier
!! value is required and must be a valid VAX/VMS file
!! specification.
!!
!! /UUDECODE
!!
!! specify that the input file is a UUencoded file and should be
!! decoded accordingly. This qualifier is provided to give
!! VVDECODE an element of backwards compatibility. NOTE: this
!! qualifier and the /XXDECODE qualifier are mutually exclusive.
!!
!! /XXDECODE
!!
!! specify that the input file is a XXencoded file and should be
!! decoded accordingly. This qualifier is provided to give
!! VVDECODE an element of backwards compatibility. NOTE: this
