CMD/Batch show variable from .txt file -

trying import list of pre-set variables , show them on screen

@echo off  cls  /f %%i in (' type list.txt ') ( echo %%i ) 

but shows what's on list , doing like.. set var=%%i echo %var% won't job. how should go doing it?

list.txt:

systemroot allusersprofile appdata commonprogramfiles computername comspec 

for /f %%i in (' type list.txt ') (  echo %%i  call echo %%i=%%%%i%% ) 

when echo called, executed echo %thecontentsof%%i%

so displays contents of required variable.

see endless articles delayed expansion if want useful.
