FOR / f之后批处理文件不继续

Question

The batch file below runs through the :RUNRULES section, executes the DO for every file in folder and after the loop executes things get funky. The IF never gets executed.

The ECHO is executed, but the echo command is not echoed, as if ECHO OFF was active. The IF is also not echoed.

::@ECHO OFF
SETLOCAL ENABLEEXTENSIONS

SET S1=Server1
SET S2=Server2
SET DATABASE=DbName
SET SCRIPT=folder\sqlscript.sql

:S1
ECHO Running rules in S1
SET SERVER=%S1%
GOTO RUNRULES

:S2
ECHO Running rules in S2
SET SERVER=%S2%
GOTO RUNRULES

:RUNRULES
SET OUTPUTFILE=%SERVER%_folder.csv
COPY NUL %OUTPUTFILE% 
FOR /f %%f IN ('dir /b /on folder') DO (
    IF EXIST results.csv DEL /Q results.csv 
    CALL RunRule "%SERVER%" "%DATABASE%" "folder\%%f" "results.csv"
    TYPE results.csv >>%OUTPUTFILE%
)

ECHO Past the FOR loop
IF %SERVER%==%S1% GOTO S2

Answer 1

The RunRule is a batch file that includes an ECHO OFF and sets the environment variable SERVER to another value, adding quotes to the value of SERVER. The IF compares the new value of SERVER to the value it was originally set to and does not execute because they are not equal.
