If you have defined a function more than once, the last function definition command executed for that function will be the one used when that function is invoked.
Yuck, that sounds like a maintenance nightmare.

It is quite common to see a main function at the top a the script. Like this:

Code:
main() {
     foo
     bar
}

foo() {
   # code for foo
}

bar() {
   # code for bar
}

# Pass script arguments into main for argument parsing
main $@

But you still need to keep the functions in the correct order, i.e callee before caller.

source

source(3tcl)						       Tcl Built-In Commands						      source(3tcl)

__________________________________________________________________________________________________________________________________________________

NAME

       source - Evaluate a file or resource as a Tcl script

SYNOPSIS

       source fileName

       source -encoding encodingName fileName													   |
_________________________________________________________________

DESCRIPTION

       This  command takes the contents of the specified file or resource and passes it to the Tcl interpreter as a text script.  The return value
       from source is the return value of the last command executed in the script.  If an error occurs in evaluating the contents  of  the  script
       then  the source command will return that error.  If a return command is invoked from within the script then the remainder of the file will
       be skipped and the source command will return normally with the result from the return command.

       The end-of-file character for files is "32" (^Z) for all platforms.  The source command will  read  files  up  to  this  character.   This
       restriction  does  not  exist for the read or gets commands, allowing for files containing code and data segments (scripted documents).	If
       you require a "^Z" in code for string comparison, you can use "32" or "u001a", which will be safely substituted by the  Tcl  interpreter
       into "^Z".

       The  -encoding  option  is  used  to specify the encoding of the data stored in fileName.  When the -encoding option is omitted, the system |
       encoding is assumed.

EXAMPLE

       Run the script in the file foo.tcl and then the script in the file bar.tcl:
	      source foo.tcl
	      source bar.tcl
       Alternatively:
	      foreach scriptFile {foo.tcl bar.tcl} {
		 source $scriptFile
	      }
