         BREAK

Command: #break

         The break command can be used inside the #foreach, #loop, #parse,
         #while and #switch statements. When #break is found, tintin will stop
         executing the statement it is currently in and move on to the next.

Example: #while {1} {#math cnt $cnt + 1;#if {$cnt == 20} {#break}}
