Comment: I need a batch file that will read the 12th character of the first line of a text file. Then I will do something based off of its value. Is this possible? I have been trying to formulate something with the FOR command but have failed. Thanks,
Matt

Reply: (edit)This will set the 12th character or the first line of the text file test.txt to the var %char%.
@echo off
set /p line=<test.txt
for /f "tokens=*" %%i in ('echo %line%') do (
set char=%%i
)
set char=%char:~11,1%
echo %char%

Reply: (edit)"Wait, I'm confused; what's the purpose of the FOR?" I'm glad it's not just me.

Reply: (edit)Sorry, got ahead of myself. I'm still learning. Everything I know about batch scripting, I learned from M2, dtech (which I never see here anymore) IVO, and Razor. Thanks guy. Let me fix it. @echo off
set /p line=<test.txt
set char=%line:~11,1%
echo %char% "Foolproof systems don't take into account the ingenuity of fools."
