Question

I have a file called “VAR.bat” that sets variables:

SET VARa=C:\Program Files
SET VARb=C:\Program Files (x86)
set VARc=C:\ProgramData

I have a file another called “SET.set” that contains just variable names:

VARa
VARb
VARc

I would like to call upon the set from a routine like this:

 for /f "tokens=* delims= " %%a in ('type "SET.set"') do (
    SET CONSA=%%~a
    SET CONSN=%%^%%a%%
    CALL :CREATEVAR
    )
    :CREATEVAR
    if exist "%CONSN%" CALL :%CONSA%_detect
    exit /b

:VARa_detect
echo "%CONSN%"
exit /b

:VARb_detect
echo "%CONSN%"
exit /b

:VARc_detect
echo "%CONSN%"
exit /b

Using the ^ to escape and add a % to a value isn’t working because the command processor interprets the value as “%VARa%” and not “C:\Program Files“

Answer 1

You could use the delayed expansion here.

setlocal EnableDelayedExpansion
for /f "tokens=* delims= " %%a in ('type "SET.set"') do (
    SET CONSA=%%~a
    SET CONSN=!%%~a!
    CALL :CREATEVAR
)

Or at the same line you could use an extra expaqnsion by CALL

...
call set CONSN=%%%%~a%%
