    A batch file issue related to EnableDelayedExpansion


    I had thought that I understood how "SETLOCAL EnableDelayedExpansion" works in a batch file in Win 10, but I'm running into something that I simply cannot reconcile.

    Take a look at the code below:

    Code:
    Explanation: I'm simply setting a variable to a path. I want my path to end with a backslash (\) so I do a simple check to make sure that it does. I use an IF structure to check for this condition and to change the variable by adding a "" to the path if needed. If I display the variable to the screen AFTER I have already added the "", the displayed variable does not reflect that change while I am still in the IF structure.

    As soon as I exit the IF structure, the variable shows correctly.

    Here is sample output:

    Code:
    My understanding was that enabling delayed expansion in a batch file should correct this. Can anyone explain to me why it is not behaving that way?

    :)
