Core Function Goto Label
From Sputnik Wiki
Goto Label; & Label:
Description
Jump to another section of the script
Remarks
This is not a universal *jump to anything you can see* it can only jump through local scopes and what not.
Think of it as a kind of multilayer break statement.
Note - People often avoid using "goto" statements in languages because they tend to be slow and a very poor way of solving a problem yet its here if you want it.
If a label cannot be found an exception will occur.
Example
goto Begin; Above: println( "Hello Above" ); goto Below; Begin: println( "Hello" ); goto Above; Below: println( "Hello Below" );
Goto can be pretty crazy in where it can jump you to for example:
{ if( "Cat" == "Dog") { if( "Cat" == "Dog") { } else { while(false) { switch(100) { case 1: { } break; case 2: { fox: say "FOX!!!!!!!!!!!!!!!!!"; goto finish; } break; case 3: { while(false) { foreach("lol" as $c) { for($i = 0; $i < 10; $i++) { for( 0 .. 30 as $k ) { cat: say "CAT!!!!"; goto fox; } } } } } break; case 4: { } break; } } } } } say "Begin"; goto test; if(1==2) { say "Test"; test: say "Hello"; } say "End"; goto cat; finish: say "OK I'm done"; // Prints: // Begin // Hello // End // CAT!!!! // FOX!!!!!!!!!!!!!!!!! // OK I'm done
