This is very easy in Tcl.
Define a proc like
proc timer_action {} {
# do the stuff here that needs to be done every 5 seconds
# ...
if {$should_keep_doing_stuff} {
after 5000 timer_action
}
}
To start the thing just use:
after 5000 timer_action
The proc itself will repost the event and so on, until
it decides it should not continue.
