Hello,

The line a want to process with the following for is like this :

TS020139,0000399AF902,1990/01/01 00:12:56

for /f "Tokens=3 Delims=," %%d in ...

It works good.

But if I have a line like this :

TS020139,,1990/01/01 00:12:56

It doesn't work anymore.

why ?
what should I do ?

Thanks for your suggestions.

It does not work because the ,, does not have a token.

Assuming the "..." in your example is a variable with a string,

@echo off
set str=TS020139,,1990/01/01 00:12:56
set str=%str:,,=,_,%
for /f "Tokens=3 Delims=," %%d in ("%str%") do echo %%d


But if the "..." is actually parsing a file, you might try,

@echo off
for /f "Tokens=*" %%d in (file) do call :GetDT "%%d"
goto :eof

:GetDT
set str=%~1
set str=%str:,,=,_,%
for /f "Tokens=3 Delims=," %%d in ("%str%") do echo %%d
 
Thanks for your answer Todd.

The thing is I don't when it will be ,, or not...

So I can't really do :
:GetDT
set str=%~1
set str=%str:,,=,_,%
Click to expand...

( i'm analysing a log file...)

If you have any idea, it's welcome
Thanks for you help again

4NT has the function @FIELD[] which observes consecutive separators:
SET text=TS020139,0000399AF902,1990/01/01 00:12:56
SET /A nF=%@FIELDS[",",%text] - 1
GOSUB dF
SET text=TS020139,,1990/01/01 00:12:56
SET /A nF=%@FIELDS[",",%text] - 1
GOSUB dF
QUIT
:dF
ECHO Text is: %text
DO n = 0 TO %nF
SET F=%@FIELD[",",%n,%text]
IFF "%F" NE "" THEN
ECHO Field %n: %F
ELSE
ECHO Field %n is empty.
ENDIFF
ENDDO
RETURN

which gives:
Text is: TS020139,0000399AF902,1990/01/01 00:12:56
Field 0: TS020139
Field 1: 0000399AF902
Field 2: 1990/01/01 00:12:56
Text is: TS020139,,1990/01/01 00:12:56
Field 0: TS020139
Field 1 is empty.
Field 2: 1990/01/01 00:12:56

@FIELD[] is documented at <http://jpsoft.com/help/f_field.htm>.

I have a batch file, when run, would RUNAS administrator
another batch file. At prompt i want to automatically
insert my password for administrator. Anyway i can have
the password in the batch file itself? so when run it
would RUNAS Admin automatically? I can then convert that
batch file to a .com file using bat2exec for security
reasons, so people cant see the password.
