The TCL interpreter manages all commands and global variables in groups. These groups are called namespaces, and commands and variables in one namespace do not affect another namespace. These namespaces are tree-organized, and one namespace command can be introduced into another namespace. The root of a namespace tree is the global namespace, which contains all the commands and variables that are not explicitly created in other namespaces.Any commands

Let's talk about the set command today. The SET command is used to assign values to a variable. It requires two parameters: variable name and variable value. In TCL, you do not need to follow the rules defined first and then used. The parser automatically creates a variable when the first value is assigned. After the value is assigned, you can use the dollar sign $ to add a variable name. Code highlighting produced by Actipro CodeHighlighter (freeware
