Purpose: Redirects execution to a labeled section of a batch file.

Syntax:

GOTO [label]

Example:

:START
ECHO Welcome!
GOTO END

:END
ECHO Goodbye!

---

🔹 6. CALL – Run Another Batch File

Purpose: Runs another batch file from within a batch file and returns after it finishes.

Syntax:

CALL [batchfilename]

Example:

CALL backup.bat

Runs backup.bat and then returns to the original batch file.

---

🔹 7. SHIFT – Handle Multiple Parameters

Purpose: Changes the position of command-line parameters passed to a batch file.

Syntax:

SHIFT

Example:
If you run:

MYFILE.BAT one two three

Inside the batch file:

• %1 = one, %2 = two, %3 = three
  After SHIFT, %1 = two, %2 = three.

---

🔹 8. FOR – Loop Through Files

Purpose: Repeats commands for a list of files.

Syntax:

FOR %%variable IN (set) DO command

Example:

FOR %%f IN (*.txt) DO COPY %%f D:\Backup
