Exceptions in Scol¶
exceptions are not yet explicitely supported.
However, you can use this method :
*_testpakS* is a Scol function. It loads a source string in the current environment without running and it returns nil if no error found or an explicit string message if an error occurs. But the program continue.
let _testpakS <string_code> -> result in
if result == nil then // no error
_loadS
else
// to do something
// continue
Something like that :
proto divideX = fun [] I;;
fun main ()=
_showconsole;
srand time;
let (((rand&255)*100)>>8)-50 -> x in // randomized value (-50 +50)
let strcatn "fun divideX () = 100 / " :: (itoa x) :: ";;" :: nil -> strCode in
let _testpakS strCode -> res in
if (nil == res) then // it's ok
(
_loadS strCode; // we load and run this part of code
_fooId divideX;
)
else // divide by zero !
(
_fooS res;
_fooId x;
1;
);
0;;
Depending on the context, you can also use the Scol functions *_testpak* or *_test_exist*.
