</td></tr></table><p class='header'>Command Description: <br><br><table width='100%' border='0' cellspacing='2' cellpadding='2' align='center'><tr><td>This command is probably just here for compatibility with other BASIC languages. LOCAL will let you specify that the variable you are defining is available ONLY to the program or <a href='Function.htm'>Function</a> you are assigning it in. In order to get a variable to be accessible anywhere in your program, you need to make it <a href='GLOBAL.htm'>GLOBAL</a>. I say it is only here for compatibility because whenever you assign a variable that isn't Global, it is automatically assigned as a LOCAL variable. You can optionally assign a value to the variable at the time of declaration. See example.</td></tr></table><p class='header'>Example: <br><br><table width='100%' border='0' cellspacing='2' cellpadding='2' align='center'><tr><td>; Local example<br>
