[Gambas-user] using try when access devices shadow the errors

[T Lee Davidson]

"there's no such information on the wiki"

Incorrect. The information IS there.

The documentation page for TRY (http://gambaswiki.org/wiki/lang/try) makes no mention whatsoever of any need to use the CATCH
instruction. You paired CATCH with TRY without any documented reason to do so. Don't blame the Wiki.

The doc page for CATCH (http://gambaswiki.org/wiki/lang/catch) specifically states, in the very first sentence, that, "This
instruction indicates the beginning of the error management part of a function or a procedure." Therefore, CATCH, not TRY, opens
an exception handling block. The immediate effect of TRY is limited in scope to a single statement or instruction.
