continue(3tcl) Tcl Built-In Commands continue(3tcl)
______________________________________________________________________________
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 4 (TCL_CONTINUE) result
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"
}
