continue

continue(1T)						       Tcl Built-In Commands						      continue(1T)

__________________________________________________________________________________________________________________________________________________

NAME

       continue - Skip to the next iteration of a loop

SYNOPSIS

       continue
_________________________________________________________________

DESCRIPTION

       This  command  is  typically invoked inside the body of a looping command such as for or foreach or while.  It returns a TCL_CONTINUE code,
       which causes a continue exception to occur.  The exception causes the current script to be aborted out to  the  innermost  containing  loop
       command,  which	then  continues with the next iteration of the loop.  Catch exceptions are also handled in a few other situations, such as
       the catch command and the outermost scripts of procedure bodies.

EXAMPLE

       Print a line for each of the integers from 0 to 10 except 5:
	      for {set x 0} {$x<10} {incr x} {
		 if {$x == 5} {
		    continue
		 }
		 puts "x is $x"
	      }
