MS-DOS package script: assignment operation

I mean below the threat of batch files: how to read a file? . To get line by line from a text file. I am using below script:

@echo off
SETLOCAL DisableDelayedExpansion
FOR /F "usebackq delims=" %%a in (`"findstr /n ^^ paths.txt"`) do (
    set "var=%%a"
    SETLOCAL EnableDelayedExpansion
    set "var=!var:*:=!"
    echo !var!
    ENDLOCAL
)

The code is working fine! The values ​​in !var!cannot be assigned to any variable. :( I'm building there, please, someone will help to read line by line, and I want to assign some variable and want to manipulate this variable. Help solve this situation.

Update:

@ECHO off

CLS

SET PROJ_DIR=D:\workspace\proj
SET PROMO_DIR=D:\TEST
SET SOURCE_CODE=\Source Code

SETLOCAL DisableDelayedExpansion
for /f %%a in (paths.txt) do (
    SET "var=%%a"
    SETLOCAL EnableDelayedExpansion
    set "var=!var:*:=!"
    set FILE_PATH=!var://www.domain.com/path/dir=!
    SET FILE_PATH=!FILE_PATH:/=\!
    SET PROMO_FILE_PATH=!PROMO_DIR!!SOURCE_CODE!!FILE_PATH! 
    FOR %%i IN ("!PROMO_FILE_PATH!") DO SET FOLDER_PATH=%%~dpi
    FOR %%i IN ("!PROMO_FILE_PATH!") DO SET FILE_NAME=%%~nxi
    IF EXIST "!FOLDER_PATH!" GOTO F3
        MKDIR "!FOLDER_PATH!"
    :F3
    IF NOT EXIST "!PROJ_DIR!!FILE_PATH!" GOTO F4
        COPY "!PROJ_DIR!!FILE_PATH!" "!FOLDER_PATH!"
    :F4
        ECHO Cannot find the file under "!PROJ_DIR!!FILE_PATH!"

    ENDLOCAL
)

The key is slow expansion, always expand variables inside brackets !not with %.

, X Y

@echo off
SETLOCAL DisableDelayedExpansion
FOR /F "usebackq delims=" %%a in (`"findstr /n ^^ paths.txt"`) do (
    set "var=%%a"
    SETLOCAL EnableDelayedExpansion
    set "var=!var:*:=!"
    set "myVar=!var!"
    set "myVar=!myVar:X=Y!"
    echo X replaced with Y =!myVar! 
    ENDLOCAL
)

goto: label for-loop

IF-

IF NOT EXIST "!FOLDER_PATH!" (
  MKDIR "!FOLDER_PATH!"
)
IF EXIST "!PROJ_DIR!!FILE_PATH!" (
    COPY "!PROJ_DIR!!FILE_PATH!" "!FOLDER_PATH!"
) ELSE
(
    ECHO Cannot find the file under "!PROJ_DIR!!FILE_PATH!"
)

FOR /F "usebackq delims=" %%a in (`"findstr /n ^^ paths.txt"`) do call :HandlePath %%a
goto :eof

================
:HandlePath
set "var=%*"
set "var=%var:*:=%"
echo %var%
goto :eof

If you want to read each line and manipulate it:

SETLOCAL EnableDelayedExpansion
FOR /F "tokens=*" %%a IN (paths.txt) DO (
set var=%%a
ECHO %var%
PAUSE
)
ENDLOCAL

If you are trying to find a line from a file and manipulate it:

SETLOCAL EnableDelayedExpansion
FOR /F "tokens=* usebackq" %%a IN (`FIND /I 'string to search for' "C:\folder\paths.txt"`) DO (
set var=%%a
ECHO %var%
PAUSE
)
ENDLOCAL

If you are trying to search a string and manipulate every word in a string:

SETLOCAL EnableDelayedExpansion
FOR /F "usebackq tokens=1-999 delims= " %%a IN (`FIND /I 'string to search for' "C:\folder\paths.txt"`) DO (
REM %%a = first word  %%b = second word etc. through the alphabet
set var1=%%a%%b%%c
set var2=%%d
ser var3=%%e
ECHO %var1% %var2% %var3%
PAUSE
)
ENDLOCAL

This works for me:

@echo off
SETLOCAL EnableDelayedExpansion

FOR /F "usebackq delims=" %%a in (`"findstr /n ^^ paths.txt"`) do (
set var=%%a
set var=!var:*:=!
echo !var!
)
ENDLOCAL
