Package: reading in a line from a file with a colon and exclamation

Question

I am trying to read a line from a file containing a colon and an exclamation mark. When I repeat this line, it only shows AFTER the colon. I need to leave the extended version turned on for more advanced code, which I will do in the do loop. But now I just want to track correctly. Any help would be appreciated!

The file will say something like:

! 12345 APX: 6.32

The code I tried was:

setlocal EnableDelayedExpansion
cd C:\Users\jwagh\Desktop\
for /f "usebackq delims=" %%a in (test.txt) DO (
setlocal DisableDelayedExpansion
 echo %%a
 set line=%%a
 set example=%line:~0,-1%
 echo %example%
)

Answer 1

, delayedexpansion , delims to ! %%a , ! (, , ! - )

for /f "usebackq delims=!" %%a in (%FamilyFile%) DO echo ^^!%%a

Answer 2

- %%a , . , - :

setlocal DisableDelayedExpansion
for /F "usebackq delims=" %%a in (%File%) do (
    set "Item=%%a"
    setlocal EnableDelayedExpansion
    echo(!Item:,-1!
    endlocal
)

setlocal/endlocal , endlocal . , endlocal , setlocal .
