I wrote the folowing code
/*******************
proc shout {} {
puts "hello";
after 60000 [shout];
}

shout
********************/

But the program prints hello world continuously without any time interval.

What i want is to print d hello world every 1 minute.

Though this will be applied in a more sohisticated context.

But the basics is enough to bootstrap me. I am a newbie to tcl/tk. Expect more of basic questions.

Feherke thanks for your helps. I will soon by like you on tcl/tk expertise.

Thanks

Hi

First, do not execute the shout, just name it.
Second, you must keep the application alive without blocking the thread. You can achieve this by using threads. ( Search for "thread" in the Tcl/Tk wiki. ) The simplest way is to run the example using [tt]wish[/tt].

proc shout {} {                                                                 
  puts "hello"                                                                  
  after 60000 shout                                                              
}                                                                               
                                                                                
shout
