C:\WINDOWS>HELP CALL
Calls one batch program from another.

CALL [drive:][path]filename [batch-parameters]

 batch-parameters   Specifies any command-line information required by the
                    batch program.

If Command Extensions are enabled CALL changes as follows:

CALL command now accepts labels as the target of the CALL.  The syntax
is:

   CALL :label arguments

A new batch file context is created with the specified arguments and
control is passed to the statement after the label specified.  You must
"exit" twice by reaching the end of the batch script file twice.  The
first time you read the end, control will return to just after the CALL
statement.  The second time will exit the batch script.  Type GOTO /?
for a description of the GOTO :EOF extension that will allow you to
"return" from a batch script.

In addition, expansion of batch script argument references (%0, %1,
etc.) have been changed as follows:


   %* in a batch script refers to all the arguments (e.g. %1 %2 %3
       %4 %5 ...)

   Substitution of batch parameters (%n) has been enhanced.  You can
   now use the following optional syntax:

       %~1         - expands %1 removing any surrounding quotes (")
       %~f1        - expands %1 to a fully qualified path name
       %~d1        - expands %1 to a drive letter only
       %~p1        - expands %1 to a path only
       %~n1        - expands %1 to a file name only
       %~x1        - expands %1 to a file extension only
       %~s1        - expanded path contains short names only
       %~a1        - expands %1 to file attributes
       %~t1        - expands %1 to date/time of file
       %~z1        - expands %1 to size of file
       %~$PATH:1   - searches the directories listed in the PATH
                      environment variable and expands %1 to the fully
                      qualified name of the first one found.  If the
                      environment variable name is not defined or the
                      file is not found by the search, then this
                      modifier expands to the empty string

   The modifiers can be combined to get compound results:

       %~dp1       - expands %1 to a drive letter and path only
       %~nx1       - expands %1 to a file name and extension only
       %~dp$PATH:1 - searches the directories listed in the PATH
                      environment variable for %1 and expands to the
                      drive letter and path of the first one found.
       %~ftza1     - expands %1 to a DIR like output line

   In the above examples %1 and PATH can be replaced by other
   valid values.  The %~ syntax is terminated by a valid argument
   number.  The %~ modifiers may not be used with %*



C:\WINDOWS>HELP CD
Displays the name of or changes the current directory.

CHDIR [/D] [drive:][path]
CHDIR [..]
CD [/D] [drive:][path]
CD [..]

 ..   Specifies that you want to change to the parent directory.

Type CD drive: to display the current directory in the specified drive.
Type CD without parameters to display the current drive and directory.

Use the /D switch to change current drive in addition to changing current
directory for a drive.

If Command Extensions are enabled CHDIR changes as follows:

The current directory string is converted to use the same case as
the on disk names.  So CD C:\TEMP would actually set the current
directory to C:\Temp if that is the case on disk.

CHDIR command does not treat spaces as delimiters, so it is possible to
CD into a subdirectory name that contains a space without surrounding
the name with quotes.  For example:

   cd \winnt\profiles\username\programs\start menu

is the same as:

   cd "\winnt\profiles\username\programs\start menu"

which is what you would have to type if extensions were disabled.



C:\WINDOWS>HELP CHCP
Displays or sets the active code page number.

CHCP [nnn]

 nnn   Specifies a code page number.

Type CHCP without a parameter to display the active code page number.
