Re: [TCLCORE] wait for some time using tcl

[Brian G. <bri...@ea...>]

Hi Swapnajit,

This is a question best asked on comp.lang.tcl.  The TCLCORE forum is  
meant for Tcl developers to discuss the internals of Tcl/Tk.

However, the answer is simple but depends on what you want to happen  
while it's waiting.  The simple command:

	after $some_microseconds

will cause the script to wait for that period of time, but it will  
block and nothing else in the program will execute.  If you expect  
some background tasks to execute, then this will not work.  You'll  
need to use:

	set ::flag 0
	after $some_microseconds set ::flag 1
	vwait flag

You may wish to post your question to the news group as you'll get a  
larger variety of answers there.
