Why is SHIFT not changing the values?

It appears that SHIFT is not working or I do not understand it. Here is the script I am trying to make work.
C:>type shiftit.bat
@echo off
echo all is %*
echo 0 is %0
echo 5 is %5
shift /5
echo shifted by 5
echo 0 is %0
echo 1 is %1
echo 2 is %2
However, I would have expected that after the shift, %1 would contain "5" or "6". It does not. It appears that the SHIFT /5 command had no effect. What am I missing?

You didn't understand right,
shift /5 will remove the argument %5, so %6 becomes %5, %7 -> %6 etc.
To remove %1 .. %5 you will have to shift 5 times.
The allargs %* is unaffected by shifting.
See changed batch
:: shiftit.bat 1 2 3 4 5 6 7 8 9
@echo off
echo all is %*
Echo %%1 IS %1
Echo %%2 IS %2
Echo %%3 IS %3
Echo %%4 IS %4
Echo %%5 IS %5
Echo %%6 IS %6
Echo %%7 IS %7
Echo %%8 IS %8
Echo %%9 IS %9
shift /5
echo shifted by 5
echo all is %*
Echo %%1 IS %1
Echo %%2 IS %2
Echo %%3 IS %3
Echo %%4 IS %4
Echo %%5 IS %5
Echo %%6 IS %6
Echo %%7 IS %7
Echo %%8 IS %8
Echo %%9 IS %9
And sample output:
> shiftit.bat 1 2 3 4 5 6 7 8 9
all is 1 2 3 4 5 6 7 8 9
%1 IS 1
%2 IS 2

That is absolutely right. It is indeed often unexpected that%*does not change on using command SHIFT one or more times without or with argument number. SHIFT affects only numbered argument references, i.e.%1,%2,%3without or with a modifier as written by LotPings, but not all arguments reference%*. That is clearly documented by Microsoft documentation on command SHIFT.
