nested For Loop

[gprashcom]

Hiya,

I am stuck with a nested for loop and variable assignement, I am trying to do the following :-

SET /a COUNT=1

IF 2 NEQ 0 (
FOR /L %%G IN (1,1,2) DO (
REM ECHO %%G
ECHO %COUNT%
FOR /F "tokens= %COUNT%-2delims=$" %%A IN ("AAA$BBB%") DO (
ECHO %%A
set /a COUNT+=1
ECHO %COUNT%
)
)
)

But the COUNT variable never seems to be incremented and always has value of 1! Could anyone please help?

Thanks for your time..

P!

gprashcom,

Don't worry, many have run into this problem before you.
The command interpreter substitutes variables before executing a block. The whole for loop is considered a block. By escaping the percent signs and CALL the command is forced to evaluate %COUNT% within the loop.

Use this line within the loop and you are fine:

Code: Select all

call echo %%COUNT%%

There are other ways, i.e.: enable delayed expansion at the beginning of you batch file and use "!" instead of "%" around a variable.

Code: Select all

SETLOCAL ENABLEDELAYEDEXPANSION
...
for ... (
    echo !COUNT!
)
