Hello,

I can't display the content of a variable in a DOS batch.
Here is my batch (the goal is to display the variable "fic" at each iteration of the loop)

for /f %%a in ('dir /b') do (
set fic=%%a
echo "%fic%"
)

I've tried: echo %%fic, echo %fic%, with quotes, without quotes, nothing works!!
If anyone sees the error, I'm open to suggestions!

Thanks in advance
Configuration: Windows XP Firefox 3.0.6

set fic = %%a
Don't put spaces around an equal sign! At least, try.

In fact, the problem isn't the assignment of a value to the variable fic (with or without space it does indeed get a value). The problem is on the echo line.

What does the echo line return to you?
Because I've always seen that you MUST put spaces in BATCH.

Here is the batch execution process. As you can see, `fic` receives a different value in each iteration (I made sure to include a space for `set fic = %%a`), but `echo` always returns the same value that corresponds to nothing... and especially not to the value of `fic`!!

W:\>for /F %a in ('dir /b') do (
set fic = %a
echo ~DF9DCF.tmp
)

W:\>(
set fic = ARC1C9
echo ~DF9DCF.tmp
)
~DF9DCF.tmp

W:\>(
set fic = EScan
echo ~DF9DCF.tmp
)
~DF9DCF.tmp

W:\>(
set fic = ExchangePerflog_8484fa312d2606bae8e1270f.dat
echo ~DF9DCF.tmp
)
~DF9DCF.tmp

W:\>(
set fic = fichier2.txt
echo ~DF9DCF.tmp
)
~DF9DCF.tmp

W:\>(
set fic = hsperfdata_ARMES
echo ~DF9DCF.tmp
)
~DF9DCF.tmp

W:\>(
set fic = java_install_reg.log
echo ~DF9DCF.tmp
)

Super Dubcek, my batch is working now!!

Weird syntax though, it's the first time I've seen that.

Thanks
