MS-DOS Commands :: goto

Overview:

Used in a batch program file to jump to a particular line.

help goto

Directs cmd.exe to a labeled line in a batch program.

GOTO label

  label   Specifies a text string used in the batch program as a label.

You type a label on a line by itself, beginning with a colon.

If Command Extensions are enabled GOTO changes as follows:

GOTO command now accepts a target label of :EOF which transfers control
to the end of the current batch script file.  This is an easy way to
exit a batch script file without defining a label.  Type CALL /?  for a
description of extensions to the CALL command that make this feature
useful.
