angleCatch errors.
Runs the first script. If it succeeds, nothing else happens.
But if it has an error (something that would otherwise result
in a red halo around the block), then the second script is run,
with the text of the error message that would have been shown in the variable ERROR.pt:tenta executar _ e, em caso de erro _ , executa _
returnThrow an error.
Makes a red halo appear around the script that runs it,
with the input text shown in a speech balloon next to
the script, just like any Snap! error.
This is useful to put in the second script of SAFELY TRY
after some other instructions to undo the partial work of
the first script.pt:lança o erro _

Catch errors in a reporter.
Evaluates its first input. If that expression successfully reports a value, this block reports that value. If the expression causes a Snap! error,
then the final input slot is evaluated with the text of what would have
been the error message in variable ERROR. SAFELY TRY then reports the value of that final expression.
Sometimes you'll want to throw an error in the final expression. You
can put an ERROR block inside a CALL block to do that.errThis block creates new variables on the selected scope: global (for all sprites), sprite (for this sprite only) or script (only for that blocks stack) with the names given (in 'names' list).
If there is already a variable with that name in that scope, it does nothing: no errors and no overwrites.pt:cria as variáveis _ _

scripteach itemvar ide = this.parentThatIsA(IDE_Morph);

ide.refreshPalette();This block deletes all the variables with the names given (inside input list).
Each name will make only one variable deletion, and this will be the variable found following the scope order: 'script' -> 'sprite' -> 'global'.
If we have a "testing" sprite variable and also a "testing" global one, deleting "testing" will delete only the sprite one (Yes! we can also do "delete var (testing, testing)" to delete both.
If one variable does not exists (in any scope) an error happens, stopping block action in that point. You can check it before with the "does var (name) exists?"block. pt:remove as variáveis _

It looks for that variable following the scope order 'script' -> 'sprite' -> 'global' (the first match it finds).

§_getVarNamesDictThis block reports the value of the variable with the name given.

§_getVarNamesDictThis block reports "true" if there is a variable with this given name (input slot) in that context.

This block turns on (show) the watcher view on stage (if it was not already activated) of the variable with the given name (slot input).
It can only access to the closest variable scope (if there different variables with the same name in different scopes) following the order 'script' -> 'sprite' -> 'global'.
