I know there is the ON ERR CALL but personally I think that fragments the code into separate methods. Having a concept of THROWS would be icing on the cake.
I’m not advocating the removal of ON ERR CALL but I would love to just do something like below for simple try/catch concepts.
I suppose this type of concept is available with 4Dv12 and PHP, but not natively.
` this is my method that is called when ANY error is thrown
ON ERR CALL("catch error")
` throws error which goes into "catch error" method call
$result:=Create document($1) ` none specified
