Next Iteration (continue)

Terminate process of a block within a caller function

Description

continue will terminate execution of a block (eg function, private, foreach, if, etc) right up until the caller function. In iteration loops like foreach and formap this will result in behavior similar to the continue statement in other programming languages.

Usage

continue block-name

Examples

%[1..10] -> foreach i {
    if { $i == 5 } then {
        out "continue"
        continue foreach
        out "skip this code"
    }
    out $i
}

Running the above code would output:

» foo
1
2
3
4
continue
6
7
8
9
10

Detail

continue cannot escape the bounds of its scope (typically the function it is running inside). For example, in the following code we are calling continue bar (which is a different function) inside of the function foo:

function foo {
    %[1..10] -> foreach i {
        out $i
        if { $i == 5 } then {
            out "exit running function"
            continue bar
            out "ended"
        }
    }
}

function bar {
    foo
}

Regardless of whether we run foo or bar, both of those functions will raise the following error:

Error in `continue` (7,17): no block found named `bar` within the scope of `foo`
