Parameters
file-spec[,...]
Specifies the names of one or more input files to be copied. If
you specify more than one input file, you can separate them with
either commas (,) or plus signs (+). Standard VAX/VMS wild cards
can be specified in file names, both Files-11 and foreign. Wild
card directories are supported for Files-11 and DOS-11 input.
The syntax for the file names is dependent on the particular
volume format option present or implied. See Section 6.0 for
descriptions of the volume format options.
Description
The EXCHANGE TYPE command transfers a file or files from the
input volume to the current output device, SYS$OUTPUT.
Qualifiers
Additional information available:
/LOG/RECORD_FORMAT/REWIND/VOLUME_FORMAT
/LOG
/LOG
/NOLOG
Controls whether EXCHANGE TYPE displays the file specifications
of each file printed.
If you specify /LOG, the EXCHANGE TYPE command displays, for each
copy operation, the file specifications of the input and output
files and the number of blocks or the number of records copied
(depending on whether the file is copied on a block-by-block or
record-by-record basis).
/RECORD_FORMAT
/RECORD_FORMAT=(option[,...])
The /RECORD_FORMAT qualifier defines the internal record
structure of a file and other attributes of the records.
Option Function
BINARY Identifies formatted binary mode transfers
FIXED Identifies fixed-length record format
PHYSICAL Identifies physical mode transfers
STREAM Identifies ASCII stream mode transfers
LENGTH Sets fixed-length record type and determines
record size
PAD Sets the character to pad short records on
fixed-length output
See section 7.0 for a complete description of the /RECORD_FORMAT
qualifier and the defaults.
/REWIND
/REWIND
/NOREWIND
Causes the input tape reel to be rewound (/REWIND) or not rewound
(/NOREWIND) to beginning-of-tape before EXCHANGE searches for the
file name specified in the input specifier.
Use this qualifier only for magnetic tapes. The /NOREWIND
qualifier is the default; use /REWIND when you want TYPE to
start searching for a file at the beginning of the tape rather
than starting at the current position.
/VOLUME_FORMAT
/VOLUME_FORMAT=option
The /VOLUME_FORMAT qualifier defines the physical format of the
volume to be processed. The default format qualifier is
dependent on the device type. The default is /VOLUME_FORMAT=RT11
for block-addressable devices mounted foreign, and
/VOLUME_FORMAT=DOS11 for magnetic tape devices mounted foreign.
The default for devices mounted native is /VOLUME_FORMAT=FILES11,
the VAX/VMS native volume format.
Option Function
FILES11 Identifies a Files-11 formatted native volume
RT11 Identifies an RT-11 formatted block-
addressable volume
DOS11 Identifies a DOS-11 formatted magnetic tape
volume
A volume format qualifier determines the format of the file name
and directory specifications, and will often imply certain
defaults. See section 6.0 for a complete description of the
/VOLUME_FORMAT qualifier and the defaults.
Examples
1. EXCHANGE> TYPE TEST.DAT
The TYPE command displays the contents of the file TEST.DAT
from the default disk and directory.
2. EXCHANGE> TYPE DYA0:BEAM.RAT/VOLUME=RT11/RECORD=STREAM
This command copies the RT-11 file to the SYS$OUTPUT device.
The two qualifiers are actually the defaults, assuming DYA0:
