E-EQ-MX2RG-L-ARC MX2 Reference Guide
VER
Type
Internal
Purpose
Displays the version number of ROM-DOS in use. Allows revision of this version number.
Syntax
VER [n.nn] [/R]
Remarks
If a new version number is specified, two digits after the decimal are required. Note that this
command revises only the record of the DOS version number; it does not change the actual
operating system loaded in the computer.
The version command shows both the version of the VER command itself and the version of DOS
in operation.
Options
The /R option shows the full version and release number of ROM-DOS.
Example
The following example changes the record of current DOS version in use to DOS 5.0. Any
programs that are executed, following this command, will recognize that DOS 5.0 is running.
VER 5.0
XCOPY.COM
External Command
The XCOPY command copies multiple files and, optionally, subdirectories from one disk to
another.
Syntax
XCOPY [source] [target] [/options]
Remarks
Use the XCOPY command to copy multiple files and subdirectories, if they exist.
The source and the target parameter are complete drive-path and file-specification descriptions.
If you do not specify a path, XCOPY assumes the default path. If a filename is not specified, then
*.* is assumed.
The ATTRIB command may be used to modify the archive bit for the various XCOPY options
that check the archive status of files. Refer to the ATTRIB command for instructions.
