Folks,

I got stuck & Need your help !!

In Tcl, is there a way to call some init_proc before calling any of
the tcl or user defined procedures.

(eg)
init.tcl
*********

proc init_proc { } {
   # Reset here all the global variable "
   puts " name of the current running proc: "
   puts " timestamp "
    ...
    ...
}

In xyz.tcl
-----------

proc xyz { } {
   puts " xyz "
}

In main.tcl
------------

puts " Execting the procedures ..."
source init.tcl
source xyz.tcl
xyz

In the above example (main.tcl), is there a way that when i call xyz (
proc) , first the init_proc should call automatically and do some
operation then the actually xyz proc should execute. I dont want to
call init_proc in every single procedure or calling init_proc before
calling any procedure ( want this operation should handle by tcl
itself ).

Also whether Is it possible to bind a event in such a way that
whenever the proc is called the event is genereated and i can handle
the event and execute some init_proc and return.

Thanks in advance any help is appreciated..
