[REBOL] Newbie getting head around TRY/DISARM
From: mat:eurogamer at: 14-Nov-2000 12:56
Hello folks,
I'm new to the list. I've been tinkering with Rebol making some damn
handy scripts. Never done anything this productive since the Amiga!
Anyhow, I've got a damn nice script that automatically uploads me some
game server log files. Unfortunately I'm having trouble trapping
errors. The examples given in the official guide basically seem broken
to me.
For example;
if error? bleet: try [ delete xUploadFile ] [
print ["* File locked, skipping..." filen]
probe disarm bleet
return false
][
Quite straight forward you would have thought. Ripped straight from an
example in the official guide. Well, it just doesn't WORK. It blows
out claiming that bleet: must have some value. So does bleet get no
value if there is no error in the try block?
Then why does the official guide have this example;
>> if error? error: try [ 1/0 ] [ [probe disarm error ]
Is this not exactly the same as my form?
Previously I had something simply in the format of;
if error? try [ delete file ] [ Whine a bit ]
But suddenly I was getting zillions of errors when there were no
errors (specifically ftp uploading). So I assume I need to disarm it
but now I can't get this form to work at all.
