Title: DO NOT CLICK // LOCAL AND GLOBAL VARIABLES IN BATCH SCRIPT // Part- 9 - LOCAL AND GLOBAL VARIABLES In this lesson, you will be learning about LOCAL AND GLOBAL VARIABLES in Batch Script. In any programming language, there is an option to mark variables as having some sort of scope. Normally, variable having a global scope can be accessed anywhere from a program whereas local scoped variables have a defined boundary in which they can be accessed. DOS scripting also has a definition for locally and globally scoped variables. By default, variables are global to your entire command prompt session. Call the SETLOCAL command to make variables local to the scope of your script. @echo off set GLOBALVAR = 5 SETLOCAL set VART = 13145 set /A VART = %VART% + 5 echo %VART% echo %GLOBALVAR% ENDLOCAL PAUSE If you have variables that would be used across batch files, then it is always preferable to use environment variables. Once the environment variable is defined, it can be accessed via the % sign. The following example shows how to see the JAVA_HOME defined on a system. The JAVA_HOME variable is a key component that is normally used by a wide variety of applications. @echo off echo %JAVA_HOME% The output would show the JAVA_HOME directory which would depend from system to system. Following is an example of an output. C:\Temp\Byte\4.0.1\jre ======================================================= If you have any questions, please post them.
