[Solved]leading digit, yet name ends in char [_,.] problem !

DOS tells me, it can't decide whether it is part of a variable because of the underscore at the end.

I have never seen a DOS error message in such "natural human language".
Did you find that in Microsoft documentation ?
Did Microsoft email that information to you ?
I or is this your interpretation ?

Please consider the possibility that '=' has very strange effects.
A very simple DOS operation "abort" within

Code: Select all

should have resulted in identical output but it aborted early, delivering only

You have focussed upon '_' but I suspect it might have been the early "abort" of your '_='

In my opinion the only problem is that ED's test scenario is too complex,
so the results can't be interpreted.

I don't understand why you experiment with the command token instead of use simple echo %2variable%

And perhaps it's more advanced to guess what happens, but in my opinion it's much easier to use ECHO ON.

Code: Select all

@echo off
setlocal
set var=content
set 1echo=set
call :test 111
exit /b

:test
echo on
echo %1var%%
echo %1var_%%
@echo off
EXIT /B

And I got the expected results, there is nothing obscure nor undefined behaviour

This is how XP32 SP2 reacts, given the following batch file.
So is my batch on my pc acting different then on yours pc

Code: Select all

@setlocal &prompt $_$G

set "2echo_=echo This causes an error"
%2echo_% See, I told you

set "2echo=echo This works"
%2echo% See, I told you

@pause
@exit /b

Code: Select all

>set "2echo_=echo This causes an error"


>echo_ See, I told you
echo_ wordt niet herkend als een interne
of externe opdracht, programma of batchbestand.


>set "2echo=echo This works"


>echo See, I told you
See, I told you
Druk op een toets om door te gaan. . .

Jeb, what is too complex ?

I tested your code and conclude the same as yall even with different results, not set a variable to begin like a parameter name

Code: Select all

@echo off &setlocal &prompt _$

set "2echo_=echo This causes an error"
%2echo_% See, I told you

set "2echo=echo This works"
%2echo% See, I told you

call :test oops
pause
exit /b

:test
echo on
echo %2echo%
echo %2echo_%
%2echo%
%2echo_%
echo off
EXIT /B

Code: Select all

echo_ wordt niet herkend als een interne
of externe opdracht, programma of batchbestand.
See, I told you

_echo echo
echo

_echo echo_
echo_

_echo
ECHO is on (aan).

_echo_
echo_ wordt niet herkend als een interne
of externe opdracht, programma of batchbestand.

_echo off

Yes I know jeb, a simple echo would be the best.
But I use echo( instead of echo., because it fails less.
But then echo( won't work in a macro unless you escape the (
And then I sometimes redirects the echos and I am pretty lazy.
That's why I use these macros, cause I'm f**king lazy

Code: Select all

set "@21echo_=>con <nul set /p ="

Yes it's all the expected correct behaviour, but your test could be more powerful.

Replace call :test oops with call :test oops XXX

Neither the 2echo nor the 2echo_ variables are ever expanded.
Each time the %2 parameter is expanded and the rest echo% and echo_% results in echo and echo_

I can't see any XP-bug nor a difference between XP and Vista
