variables expansion inside for in batch

Question

I am new to batch and I don\'t understand when to use late variable expansion or normal expansion. Below I have a test script in which I have tested the variables expansion.

Answer 1

This can work depending on the text being parsed, as poison characters can affect it.

@echo off
set var=0
echo late var=%var%
echo var=%var%

for /F "delims= " %%A in (temp.txt) do call :next "%%A"
goto :EOF
:next
        echo Analyzing %~1
        set line=%~1
        echo line=%line%
        echo late line=%line%
