Conditional try statement

Question

Greetings, all. I'm trying to create a loop that is conditional on the successful completion of a try statement. It'd look something like this:
try
Close Tab in Safari
end try
if (try worked)
run an application
loop from beginning of try
else
end loop
Any suggestions on how to code this?
Cheers,

If you have tabs enabled, you can "sorta" script tabs. Here are two examples
tell application "Safari"
activate
repeat
set oneURL to URL of the front document
if oneURL is not in theURLs then
set end of theURLs to oneURL
tell application "System Events" to keystroke "}" using {command down}
else
exit repeat
end if
end repeat
end tell
-- If you want to close the window with multiple tabs showing then uncomment the line below
--tell application "System Events" to keystroke "w" using {shift down, command down}
theURLs
and to create new tab, the same trick:
tell application "Safari"
activate
tell application "System Events" to keystroke "t" using {command down}
end tell
