"Command" vs "On" command

[raugert]

What's the difference between the following for creating custom commands ?

Code: Select all

command doSomething
-- code
end doSomething

VS

Code: Select all

on doSomething
--code
end doSomething

Is is something to do with the message path ? The reason I ask is because my app was crashing occasionally when I was using "command" in a button script. I changed it to "on" and it seems much more stable ...

I still use "command" for custom commands in the card script. It doesn't seem to affect anything.

Can anyone clarify,
thanks,
Ricard

Switching between "on" and "command" should make no functional difference. Please post the code in question and we may be able to help figure out what you're seeing.

Hi Ricard,

what Richard said!

Once upon a time (some years ago) Livecode advised use to use COMMAND for custom handlers to differ them from the build-in commands like "on mouseup" etc.

They said that at some point in the future this would really matter.
This day did not arrive yet, however!

Thanks Klaus and Richard. That answers my question. I didn't think it made any difference. The crashing issue I had, thats now fixed, must be something else I did.

cheers,
Richard
