This bug can be avoided by always using CALL. The CALL command will pass control to the statement after the label specified along with any specified parameters. To exit the subroutine specify GOTO:eof this will transfer control to the end of the current subroutine.

The first echo command is never run as the batch script jumps to the specified goto command. From that point forward, the script executes line-by-line. In the previous example, you defined labels with an underscore. There are several caveats to keep in mind, as not just any label will work. Adding various control characters will cause the batch script to run forever in a loop and require manual termination. To add more practicality, what if you needed a batch script to run some commands only if a certain condition were true?

The goto command used in conjunction with the if command gives you control over exactly when that jump is made. For example, check out the below example. In this example, the batch file is using the call command to run a program. If so, it skips to the end of the script.

Otherwise, it runs the echo command to tell you that an error has occurred and then skips to the end of the batch script. Now that you have learned the basics of a goto statement, how about using the goto command with a subroutine? A subroutine is like a block of code or a function that you can call to execute.
