Trouble ignoring error -1700

Scripting Forums AppleScript | Mac OS X
#1

Hi,

I have this application where any unexpected errors are written to a log using a subroutine. I expect errors 3 and -1700, but -1700 won’t get ignored.

try
			(*Do some stuff*)
		on error err number num
			if (num ≠ -1700) and (num ≠ 3) then write_log from (err & " (" & num & ")")
			(*Do some stuff*)
		end try

Anyone know how to fix this? -1700 would clog up the log file a lot.

Hi,

what’s about debugging the code?
unexpected errors are uncool :wink:

the logic in your script is
(not 3) and (not -1700)
– 3 1700
– is not is not → log
– is is not → log
– is not is → log
– is is → not log

but you want NAND, which is in fact OR
(not 3) or (not -1700)
– 3 1700
– is not is not → log
– is is not → not log
– is not is → not log
– is is → not log

#3

(num ≠-1700) OR (num ≠3) produces a log for both of them.
Do you mean EXOR (Exclusive OR)?
If so, how am I supposed to do that in AS?

#4

you’ re right, I’ve tried to think too much outside the box :wink:

simulating error -1700, this works

try
	"B" as integer -- causes error -1700
on error number num
	if (num ≠ -1700) and (num ≠ 3) then say "log"
end try
#5

You’re right, that works.
But a different cause seems to have a different effect.
err = Can’t make characters 2 thru -1 of “~” into type Unicode text.
num = -1700

Even something like (num does not contain “characters”) produces a log.

Sorry about all this. I’d put (num ≠-1700) in the wrong place, not realising there was another try statement in the other section.
But thanks for you’re time.
