Within a function, I need to delay the execution of an httpios::geturl call by a couple of seconds.
 
I read that there is no sleep function in TCL and that I should use after instead.
 
Using the after command I get the following error:
 

   Mar 21 18:04:52.198: TCL script failure 
Result:
   invalid command name "after"

 
Is after not available somehow?
 
I would believe, according to[1] that the function is available.
 
I'm calling the function like so:
 
  # wait 10 seconds
  after 10000
 
thanks for any help!
