Hello:
please find out the problem for me that why my code can not work.
 
 set i 10
 if { $i == 10 }
    puts $i

thanks

  set i 10
  if { $i == 10 } { puts $i }

or

  set i 10
  if { $i == 10 }   { puts $i }

or

  set i 10
  if { $i == 10 } { 
    puts $i 
  }

The if command takes two or more arguments. The first beeing the test.
A litteral between braces can contain newlines.
A \ at the end of the line joins the current line and the following line.

For more you need to read the endekalogue (the eleven rules):

http://mini.net/tcl/Endekalogue

And the if page of the Tcl manual:

http://mini.net/tcl/if
