Miguel,
Sorry but you are mixing 2 different issues. The TRY construct in all
those languages will still raise the exception, if you have any
error. The CATCH syntax simply allows you to have different catchers
for different errors, at different levels. Those samples you posted
function exactly like this:
TRY
? a /0
CATCH e
SWITCH e:genCode
CASE EG_ZERODIV
? "Caught division by 0"
EXIT
DEFAULT
Throw( e )
END
FINALLY
? " In finally"
END
As to the recursive limits of FOR EACH and WITH OBJECT, I'll try to
remove the limit as as I get a chance, or you can do it if you need
it sooner.
