I have a two dimension arrary and want to check whether an element exist or not. <br />
<br />
I have googled and got an answer to use &quot;info exist array(index)&quot;. However, it seems to be not applicable to two dimension array, as I got error messages as<br />
wrong # args: should be &quot;info exists varName&quot;<br />
<br />
Any idea?

A scripting language is a programming language that supports scripts, programs written for a special run-time environment that automate the execution of tasks that could alternatively be executed one-by-one by a human operator. Scripting languages are often interpreted (rather than compiled). Primitives are usually the elementary tasks or API calls, and the language allows them to be combined into more complex programs. Environments that can be automated through scripting include software applications, web pages within a web browser, the shells of operating systems (OS), embedded systems, as well as numerous games. A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, this is also known as an extension language.
