[Gambas-user] Probably a really dumb question about Error

[Jussi Lahtinen]

Depends on your needs. You can use Try without Error, if you don't need to
handle the error situation, but that's bit weird and probably not the right
way to do what ever you try to do. Otherwise I use it like this:

Try something

If Error Then
  do something
  Error.Clear
Endif

So, you need to clear the error, only when there is something to be
cleared. Or if you don't handle the errors, then just clear after all the
Try commands.
