how can you get from the nth-parameter on? I want to pass everything from
the 2nd parameter on to another batch file. I am currently passing it %2 %3
%4 %5 ... %9 (not that I anticipate ever having more than nine parameters,
but who knows?)

Try this
@echo off
set var=%*
call set var=%%var:*%1=%%
echo %var%

It couldn't work properly if two or more parameters are equal

Hello Foxidrive,
took me a bit longer for a solution. And then I had to test yours.
I see a problem when an argument is conatined in another one. Of course
this example is a construed one to output from the 4th.

Here is a snippet from a script I wrote to build a Winamp playlist from the
songs I have selected in my file manager. There are usually far more than
9 songs selected, this reads them in one at a time and builds a playlist
file of them.

:: WITHIN THIS LOOP IF %1 IS A NULL THEN IT'S TIME TO BOOGIE

shift /1
goto:loop

I made a slight modification to remove the trailing space from the first
parameter showing up as a leading space in the new parameter list:
call set var=%%var:*%1 =%%
and it seemed to work fine.
Why do you have to "call" the 2nd set command for it to work?

I was referring to a more general case

set var=%*
call set var=%%var:*%10=%%
echo %var%

Yes, and that may have been what Marco meant too, but for the stated task
it works fine AFAICS.
To Frank - the call and added percent signs in the set command forces the
variable %1 to be evaluated, whereas without the call it can't be used with
that syntax.
foxidrive
Sorry to say Marco, but it fails the simplest test.

I personally am guilty of concentrating on the aim of the question, and
disgarded the more general "nth-parameter on" portion, so my solution is
only good for case above.

Hi Marco,
I see a problem with quoted arguments here.
Thats why my version uses a call %* to resemble the same parsing
algorithm. Of course >|< & will be difficult to escape/quote properly.

What about this?
@echo off
setlocal enabledelayedexpansion
set a=%%3
for /l %%b in (4 1 9) do set a=!a! %%%%b%
call echo.%a%

Nice. More direct. But limited to the remaining 6 of 9 arguments.
When you shift and then take the remaining it still suffers from being
stuck to the max 9 reachable parameters via %1..%9.
And the OP's question was how to overcome that limitation.

Ah,yes,and this one?

Provided ther is no equal sign in any of the arguments 1-4 it will do
better.

Yes it doesn't work only with =, while yours doesn't work with <|>

This task is not quite as trivial as it first appears to be. There
are a couple subtle pitfalls. Since the solution uses shift it
"destroys" the parameters from later usage, so they have to be
stored. The logic is that if one wants to count the parameters, one
is likely also to want to use the parameters! Also note the usage of
[] in the if testing lest there is confusion with parameters
potentially enclosed in quotes. If one needs a parameter count, it
is logical and sensible to always put it as the first thing into the
script. The denotations in the example below have clear UNIX
connotations.
@echo off & setlocal enableextensions enabledelayedexpansion
set /a argc=0
:_argcLoop
if [%1]==[] goto _exitargcLoop
set /a argc+=1
set arg%argc%=%1
shift
goto _argcLoop
:_exitargcLoop
::
:: Show the results
echo The number of parameters is %argc%
set /a count_=0
:_dispLoop
set /a count_+=1
if defined arg%count_% (echo !arg%count_%! & goto _dispLoop)
::
endlocal & goto :EOF
An example:
D:\TEST>cmdfaq one two "the third"
The number of parameters is 3
one
two
"the third"
If you wish to omit the quotes (") substitute
set arg%argc%=%~1

OK, so below is my solution. It does not use shifting, but it is an external
batch utility. I expect it could be encoded as an internal routine, i.e.
"call:getarg varname 3 5 %*".
It creates a variable (whose name is its first parameter) to contain all
parameters from {begin} to {end}, suitable for passing on to another batch
file. If the calling routine needs to extract individual parameters
separately, this could be done by setting the end parameter to the same
value as the bgn parameter.

IF, as IIRC it *may*, %* will pass all the arguments, then ISTM that a
batch file could call another batch file to count them with shift; and,
moreover, could call WSH using javascript or vbscript to determine the
number very easily (for the WSH part, see my batfiles.htm#WSH for
detail.
I assume that standard output can be captured to the environment.
