         BREAK

Command: #break

         The break command can be used inside the #else, #elseif, #if, #foreach,
         #loop, #parse, #switch, and #while 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}}
