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.
Lars H: Or use breakeval as follows
foreach i $List1 {
breakeval-aware foreach j $List2 {
if {[some condition]} then {
breakeval {continue} ; # Break out of j loop, do a continue for the i loop.
}
eval {blah blah blah}
}
}MG April 20th 2005 - In PHP, continue (and break) accept an argument that tells it how many nesting levels to continue/break for, slightly-similar to return's -code option. How hard would it be to add something like that into Tcl? Since neither break nor continue accept any arguments right now, as long as it defaulted to 1 it would have total backwards-compatability, and would, IMHO, be more "natural" than the above.
