Does that mean the meaning of break depends on context ?
Yes, just like exit or continue or retry (the last two are new in 4.0). This is to prevent having to invent extra flags and create extremely convoluted control flow:
integer exit_i = 0 for i = 1 to 10 do for j = 1 to 10 do if foo(j) > bar(i) then exit_i = 1 exit end if end for if exit_i then exit end if end for
That code could (in 4.0) be simplified:
for i = 1 to 10 label "i" do for j = 1 to 10 do if foo(j) > bar(i) then exit "i" end if end for end for

Thanks Matt, but what I was trying to ask concerning context was:
- break inside a switch aborts the switch;
- But if the switch is inside an if-then statement, break aborts the if-then ?, i.e., break works different if the switch is inside an if-then or not ? IIUC, Jeremy replied that break doesn't depend on the context.
Maybe this example helps me:
X = 1 condition = 1 switch X do case 1 then if condition then break end if X = 2 end switch ? X
If that is valid, what will be showed ?
