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 (%
) 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
