Applescript error codes?

[AJB_UMASS]

Is there a way to check if a _specific_ error occurred? It seems like if you use the TRY command, you can trap error conditions, but there's no method for seeing what the problem actually was.

Does anyone have a way to check this? Does there exist a list of numerical equivalents for Filemaker Applescript errors?

Never mind - I figured it out.

Here's what works:

try

tell application "FileMaker Pro"

activate

go to window "abc"

do script "xyz"

end tell

on error number errNumber

if errNumber = -1728 then

tell application "FileMaker Pro"

getURL "fmp7://usename:[email protected]/abc.fp7"

delay 5

do script "xyz"

end tell

end if

end try

The DELAY command isn't necessary; but for my example, the database needs a few seconds to total some info, when opening for the first time. The "-1728" error code is the numerical equivalent to "Object not found".
