問題與我的批處理腳本

Question

我仍然在學習語言，所以請放縱。

在下面的代碼中與我的START變量相關的條件從不觸發，我找不到原因。如果當前行以「80 /」開頭，並且前面的行以分號和空格開始，那麼該部分應該執行。可能是一個synthax錯誤或一些這樣的。任何幫助將不勝感激。

@ECHO OFF 
SETLOCAL DISABLEDELAYEDEXPANSION 

>"%~dpn1_2.txt" (
    FOR /F "tokens=1* delims=]" %%j in ('find /V /N "" %1') DO (
     SET "currentLine=%%k" 
     SETLOCAL ENABLEDELAYEDEXPANSION 
     IF "!currentLine:~0,2!"=="; " (
      SET START=1 
     ) ELSE IF "!currentLine:~0,3!"=="80/" (
      IF "!START!"=="1" (
       SET "currentLine=!currentLine:~0,2!!currentLine:~3,5! !currentLine:~18!" 
       SET START= 
      ) ELSE (
       SET string=!currentLine:~0,2!!currentLine:~3,4! 
       FIND "!string!" labels.txt > nul 
       IF !errorlevel! EQU 0 (
        SET "currentLine=!currentLine:~0,2!!currentLine:~3,5! !currentLine:~18!" 
       ) ELSE (
        SET "currentLine=   !currentLine:~18!" 
       ) 
      ) 
     ) 
     ECHO(!currentline! 
     ENDLOCAL 
    ) 
)
