To comment out code in a batch file, you can use the `REM` command or simply add a semicolon (`;`) at the beginning of the line. Here’s an example: “`batch @echo off ; This is a commented line using a semicolon REM This is another commented line using the REM command echo Hello, World! “` In this example, both the semicolon and `REM` are used to comment out lines, making them non-executable.

To effectively comment out code in a batch file, you can utilize either the REM command or a semicolon ( ;) at the beginning of the line. Here’s an organized explanation and example to illustrate both methods:

Methods Explained:

Using REM Command:
The REM (remark) command is specifically designed for adding comments in batch files.
Lines starting with REM are ignored by the interpreter, making them ideal for documentation purposes.
Using Semicolon (;):
Placing a semicolon at the start of a line treats the entire line as a comment.
This method is useful for temporarily disabling code lines without altering their structure.

Example Script:

@echo off

; This line uses a semicolon to comment out
REM This line uses REM to add a comment

echo Hello, World!

@echo off

; This line uses a semicolon to comment out

REM This line uses REM to add a comment

echo Hello, World!

Explanation of the Example:
– When this script runs, it will execute echo Hello, World! and ignore both commented lines.
– Using REM is preferred for clarity, while semicolons offer a quick way to disable code.

Best Practices:

Use REM for readability and explicit commenting.
Use ; for temporary disabling of code lines quickly.

Both methods are effective for different purposes, allowing flexibility in how you annotate or disable parts of your batch file.
