Prompt; Rd (Rmdir; Rem; Reboot - Hand Held Products Dolphin 7200 User Manual

Syntax: PAUSE

PROMPT

The PROMPT command maintains the PROMPT environment variable that is used by COMMAND.COM to display something
before the user is asked to type-in a command.
The default PROMPT variable is $n$g. This has the effect of showing the current drive letter followed by a "greater-than" sign:
Syntax: PROMPT string

RD (RMDIR)

The RD command removes a subdirectory from a root directory or of a subdirectory. This command can only be used to delete
directories, and cannot be used to delete files, even if they are inside the directory to be removed. Conversely, the DEL
command cannot delete directories; only the files they contain. If a drive is specified, then the directory on the specified drive is
removed. Otherwise, the default drive is assumed.
Syntax: RD [drive:]path

REM

The REM command provides a simple way of entering a free-form comment in a batch file. The line starting with REM has no
effect on the execution of the batch file.
Syntax: REM any comment

REBOOT

The REBOOT command will reset the terminal.
Syntax: REBOOT

REN

The REN command renames a file or group of files. Files cannot be moved in the directory structure with this command; instead,
only their filenames are altered within the directory in which they reside. Wildcards may be used in the second pathname to
indicate that the characters in that component of the first filename are to be kept as-is.
Syntax: REN [drive:][path]filespec filespec

SHIFT

The SHIFT command allows access to multiple batch file arguments. The command shifts the contents of the 9 batch file
arguments so that %2 is copies into %1, %3 is copies into %2 and so on.
Syntax: SHIFT

SET

The SET command displays the entire environment space (one variable per line), or changes the assignment of one variable in
the environment space. If no operands are specified, then the SET command simply displays all of the environment variables in
the environment space. If a variable name and an equal sign is given, but no string is specified, then the variable name is removed
from the environment space. If the string is specified, then the previous definition of the variable is deleted, and the new one is
installed in the environment.
