How TCL works..
---------------
After TCL installed on the machine, TCL information got
registred in the machine.
e.g:In Windows Registry
[HKEY_LOCAL_MACHINE\SOFTWARE\ActiveState\ActiveTcl]

The TCL path is updated in Machine environment.
e.g:
PATH=C:/Tcl/bin;%PATH%

Then TCL starts working.

1.TCL a Scripting Language. TCL binary comes with
name "tclsh".
When we use TCL,[ For example from Command prompt/Terminal
try to run tclsh ] it provides default prompt "%" to User
and asks for input.
#tclsh
%

How TCL works??
---------------
Each input from user is treated as TCL command.
After providing the command, tclsh fetch(gets) that command
and try to validate/compile/execute and populate(puts) the
message.

#tclsh
% hello
invalid command name "hello"
% set
wrong # args: should be "set varName ?newValue?"
%set say "Hello"
Hello


2. When we use TCL, we can provide a Script file as
argument.
Example: Create a file "HelloTickle.tcl" containing:

set say "Hello"
puts $say

Execute:
#tclsh HelloTickle.tcl
Hello

How TCL works??
---------------
Tcl takes the Argument as a file and try to read the file.
TCL stores the file in memory and reads the file Line by
Line and try to validate/compile.
TCL provides the output and release the memory.
