----
Suppose the following code:

 foreach  i  $List1  { 
 
     foreach  j  $List2  { 

        if  [some condition] {continue}

        eval {blah blah blah}
     }
 }

[Continue] interrupts the foreach j loop. But what if I wanted it to break the foreach i loop?

Place the [[foreach i]] command in a proc and use [return]
instead of [continue].
